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.

Q: If you take the fastest speed of a rabbit and double it, add 4 to that then double it again you get 188. How fast is the rabbit?
A:
You doubled a number to get 188 so in reverse, you would divide by 2 so 188 / 2 = 94. You added 4 to this number and in reverse, you would subtract by 4 so 94 - 4 = 90. You doubled a number to get 90 so in reverse you would divide by 2 so 90 / 2 = 45 is the fastest speed. The answer is 45.
