Answer this question:Michelle had some leftover cans of silly string from her birthday party. She split them among Roger and 3 of his friends. Then Roger decided to give 2 of his cans to his brothers so that he now has 4 for himself. How many cans of silly string did Michelle have to start with?
Roger originally had 4 cans of silly string + 2 can he gave to his brothers = 6 cans. Since his friends received the same amount as Roger did originally, 3 friends x 6 cans of silly string = 18 cans. Michelle started with 6 cans that went to Roger + 18 cans that went to his friends = 24 cans of silly string.
The answer is 24.

Answer this question:Cordelia is dyeing her hair red. To get the color she wants, she first has to bleach her dark brown hair to blonde, and then she has to apply the dye. The whole process will take 9 hours. Dyeing takes twice as long as bleaching. How many hours will it take Cordelia to bleach her hair?
Let H be the number of hours it takes Cordelia to bleach her hair. A dye treatment takes twice as long, so it takes 2H. Thus, bleaching and dying will take H + 2H = 3H = 9 hours. Therefore, it will take Cordelia H = 9 / 3 = 3 hours to bleach her hair.
The answer is 3.

Answer this question:If Pete read twice as many books as Matt did last year, and this year he doubles that number while Matt reads only 50% more, how many books does Pete read across both years if Matt read 75 books in his second year?
First, we need to find the amount Matt read both years to establish what Pete read, so to find Matt's first - year total we multiply 75 / 1.5 = 50 books the previous year. Since Pete read twice as many books as Matt did in the first year, and Matt's first - year total is 50, this means Pete read 50 * 2 = 100 books his first year. Since Pete doubled the number of books he read the following year, this means Pete read 100 * 2 = 200 books the following year. We add the two years of Pete's reading together to find 200 + 100 = 300 books read in total.
The answer is 300.

Answer this question:Nigella is a realtor who earns a base salary of $3,000 a month plus a 2% commission on every house she sells. One month, Nigella sells 3 houses and earns $8,000 total.

First figure out how much money Nigella earned from commission by subtracting her base salary from her total earnings: $8,000 - $3,000 = $5,000. Next, figure out how much all three houses cost by dividing Nigella's commission money by her commission rate: $5,000 ÷ 0.02 = $250,000. Next, express each house's price in terms of A's price: B = 3A, and C = 2A - $110,000. Now we know that A + 3A + 2A - $110,000 = $250,000. We can combine like terms to find that 6A - $110,000 = $250,000. Now we add $110,000 to both sides of the equation and get 6A = $360,000. We can divide both sides by 6 to find A = $60,000.
The answer is 60000.
