7% of the cost is 34,000.\n\n'of' means multiply; 'is' means equals.\n\n0.07C = 34,000\nC = 34000/0.07 = 485,714.29\n\nI think your book is rounding.

1) \nSB takes 3 hours to do the job.\n\nfraction of job done by SB in 1 hr = 1/3\n\nSimilarly Fraction of job done by SW in 1 hr = 1/2.5 = 2/5\n\nFraction of job done by both SB and SW in 1 hr = 1/3+2/5 = 11/15\n\nNow Both SB and SW can finish the job together in : 1 / (11/15) = 15/11 = 1.36 hrs.\n\n Shortcut:\n\n1 / (X and Y together) = 1/ X + 1 / Y\n\n2)\n\nNow when Mark and his agent meet they would have covered the 500 Kms together as they \n\ntravel the same road to meet each other.\n\nsuppose after x hrs they meet.\n\n\nMark has travelled : 55x km\nAgent has travelled : 65x km\n\nTotal distance : 55x + 65x = 500\n\n120x = 500 => x = 500/120 = 4.167 hrs\n\n3) Use the same approach as in 1) above.\n\nUse the shortcut too if u need.\n\n1/ ans = 1/12 + 1/9\n\nand find the ans!\n\n4)\n\nLet the cost of the pencil be x.\ncost of pen = 3x\n\n5 * x + 4 * 3x = 4.25\n17x = 4.25\nx = 0.25\n\nSo pencil costs 25 cents!\n\n\nHope the above answers help!

You want to make all your fractions have the same denominator, so, say we pick 90. 40 x 2.25=90, so 1/40 is the same as 2.25/90 (for B).\nDoing the same thing with C 12 x 7.5 = 90, so 1/12= 7.5/90.\n\nNow, you can relate the workers. A= 1/90, B= 2.25/90 and C= 7.5/90.\nThat means that A gets one share, B 2.25 shares and C gets 7.5 shares. So, set Rs 360 equal to the total number of shares, which is 1 + 2.25 + 7.5 or 10.75. Divide 360 by 10.75 to get the 'value' of a share. 360/10.75 = 33.488.\nThat means A gets 33.488, B gets 2.25 x 33.488 = 75.35 and C gets 7.5 x 33.488 = 251.16\n\nSo, your answer is D.

Write them as a ratio of integers (cents) first:\n1250 / 875\n\nRemove a common factor of 5 from top and bottom:\n250 / 175\n\nRepeat for another 5:\n50 / 35\n\nOops, we can do it again:\n10 / 7\n\n(Note: this is equivalent to 1.428571... in decimal, so the previous answer was right about this, but the problem asked to do it as a ratio of whole numbers.)\n\nSo the ratio of the prices is 10 / 7.

1) x spent on rest, x + 600 on food, x+x+600 = total spent\ntotal salary = 5/3 * spent = 5/3*(x+x+600)\n\n5/8*(x+x+600) = x+600\n375-600 = -1/4(x)\n900 = x (on rest)\n1500 (on food)\nspent total of 2400\ntotal salary = 4000\nsaved = 2/5 of total = 1600\n\n2) if it took 20 minutes (from 10:15 to 10:35) to change 50 degrees (20*2.5 = 50)\nand it took 30 minutes to change back 37.5 degrees (50-12.5=37.5) \n\nThen, the rate of cooling is 37.5 degrees/30 minutes = 1.25 degrees / minute of cooling\n\nTherefore, it took ten minutes of cooling to change 12.5 degrees, which means the time at which it was 12.5 degrees hotter than 11:05 was 10:55 pm.\n\nP.S. you have one tough teacher!  glad to see that you are getting a good education, cause these are not easy questions.

Everything is supposed to add up to $25 not $30. Think of it like this...\n\n$30 was paid to the manager. SO he has $30. HE took out $5 from this to give them back...so in essence he has $25 in his possession. \n\nThe three people paid $30 and were given back $3 ($1 EACH) Therefore they actually paid $30 - $3 = $27. The bellhop kept $2 which when subtracted from the $27 would give equate the $25 in the possession of the manager.\n\nThe trick in the question was adding back the $2 that the bellhop had, instead of subtracting.

It is *traditional* to give gifts of 18, 36, or 54.  It isn't *required*, and you won't look like an idiot if you give a different amount.  If you buy a gift instead of cash (or gift certificate), the amount you spend wouldn't necessarily be in multiples of 18.  The word for "life" in Hebrew has a numerical value of 18; this is the reason for the tradition.  But I'm sure your friend would rather get $25 than $18.  :-)

OK.\n\nThe problem specifies that x is the amount John gets a week, so we need to express everything in terms of how much John gets.\n\n"Peter gets twice as much pocket money as John"\n\nP = 2x\n\n"George gets $3 less than Peter"\n\nG = P - 3 = 2x - 3\n\n"Altogether the three boys get $17"\n\nx + P + G = 17\nx + 2x + 2x - 3 = 17\n\nYou can solve from there.

I usually don't do this because I firmly believe this category shouldn't even be here and kids should be doing their own homework.  But you asked nicely, and mostly had good punctuation and grammar, so I will help you.  But, I'll help you by showing you how to get the answer and not just giving it to you, ok?\n\nIf you subtract $75 from $60 you get $15, right?  So if you divide that $15 by the original $60, you get .25 which is 25%.  And to verify it, you take your original $60 jacket, multiply it by 25% and add that markup to the $60 and you get $75.  So, the markup is 25%.
