[Question]Basil gets 1/2 of a dog cookie in the morning and before bed. She gets 2 whole cookies during the day. Basil’s cookies are packaged with 45 cookies per box. How many boxes will she need to last her for 30 days?
[Answer]Basil gets 1 / 2 in the morning and 1 / 2 at bedtime so she gets 1 / 2 + 1 / 2 = 1 whole cookie. Basil also gets 2 whole cookies during the day so all total she gets 2 + 1 = 3 whole cookies. She needs cookies for 30 days and eats 3 a day so she needs 30 * 3 = 90 cookies. Her cookies come 45 per box and she needs 90 cookies so she needs 90 / 45 = 2 boxes of cookies. The answer is 2.
Q: Lance has 70 cents, Margaret has three-fourths of a dollar, Guy has two quarters and a dime, and Bill has six dimes. How many cents do they have combined?
A: Margaret has 100 * 0.75 = $0.75. Guy has $0.25 + $0.25 + $0.10 = $0.60. Bill has 6 * $0.10 = $0.60. Lance, Margaret, Guy and Bill have $0.70 + $0.75 + $0.60 + $0.60 = $2.65. Thus they have $2.65 * 100 = 265 cents. The answer is 265.
