Q: Mrs. Amaro has 80 roses in her garden. Three-fourths of her roses are red, one-fourth of the remaining are yellow, and the rest are white. How many of Mrs. Amaro's roses are either red or white?
A: Mrs. Amaro has 80 x 3 / 4 = 60 red roses. So, 80 - 60 = 20 roses are not red. Then, 20 x 1 / 4 = 5 of those 20 non - red roses are yellow. Hence, 20 - 5 = 15 roses are white. Therefore, 60 + 15 = 75 roses are either red or white. The answer is 75.

If her skirts are $20.00 each, the blouses are $15.00 and both pairs of pants are $30.00 each. How much will she spend on her wardrobe?
Answer: The pants are $30.00 and are buy one get one 1 / 2 off so the second pair will be 30 * .5 = $15.00. The first pair of pants is $30.00 and the second pair is $15.00 so the pants cost 30 + 15 = $45.00. The skirts are $20.00 each and she's buying 3 so that's 20 * 3 = $60.00. The blouses are $15.00 each and she's buying 5 so that's 15 * 5 = $75.00. All total, her wardrobe will cost $45 for the pants, $60 for the skirts and $75 for the blouses so 45 + 60 + 75 = $180.00. The answer is 180.

Q: Jenna wants to buy a concert ticket that costs $181, plus five drink tickets for $7 each. If Jenna earns $18 an hour and works 30 hours a week, what percentage of her monthly salary will she spend on this outing?
A: First find the total cost of the drink tickets: 5 tickets * $7 / ticket = $35. Then add that cost to the cost of the ticket to find the total cost: $35 + $181 = $216. Then multiply Jenna's hourly rate by the number of hours she works each week to find her weekly earnings: $18 / hour * 30 hours / week = $540 / week. Then multiply her weekly earnings by the number of weeks she works each month: $540 / week * 4 weeks / month = $2160 / month. Then divide the cost of the concert by Jenna's monthly earnings and multiply by 100% to express the answer as a percentage: $216 / $2160 * 100% = 10%. The answer is 10.
Question: A zoo has 8 parrots. It 3 times the number of snakes than parrots and 2 times the number of monkeys than snakes. The number of elephants is half the number of parrots and snakes added up, and there are 3 fewer zebras than elephants. What is the difference in number between the zebras and the monkeys?
Answer:
The zoo has 8 x 3 = 24 snakes. It has 24 x 2 = 48 monkeys. The number of parrots and snakes added up is 8 + 24 = 32. There are 32 / 2 = 16 elephants. There are 16 - 3 = 13 zebras. The difference between zebras and monkeys is 48 - 13 = 35. The answer is 35.
