Yves goes apple picking at an apple orchard. The apple orchard charges $8.50 per hour, during which a customer is allowed to pick as many apples as possible. If Yves picks approximately 50 apples per 1 hour, and he picks 75 apples at the orchard, approximately how much money can he expect the apple orchard to charge him?
Choice D is correct. Since Yves picked 75 apples and picks approximately 50 apples per hour, it can be determined that he picked apples for 75/50=1.5 hours.
Because the apple orchard charges $8.50 per hour, Yves can expect to be charged $8.50*1.5=$12.75.
Yves can expect the apple orchard to charge him $12.75.

While driving from Orlando, Florida, to Tampa, Florida, a family travels 4 miles in 5 minutes. If they travel at the same rate for the next half hour, approximately how many miles will they travel in that half hour?
Option B is correct. 30 minutes is six times as long as 5 minutes, so the car will travel six times as far as it traveled in 5 minutes, or 4*6 miles.
