Answer 1

15. After 9 days, the school nurse's office will use 9 x 47 = 423 Band-aids, so there will be 500 - 423 = 77 Band-aids left in the box.

16. After 6 days, the pediatrician's office will use 6 x 83 = 498 stickers, so there will be 500 - 498 = 2 stickers left.

17. The athletic trainer orders 8 x 32 = 256 rolls of tape. For the first 3 months of football season, which is 12 weeks, the athletic trainer will use 20 x 12 = 240 rolls of tape. Therefore, the athletic trainer will have 256 - 240 = 16 rolls of tape left.

18. In the first four hours, the dentist examines 8 x 4 = 32 patients. To reach the goal of 50 patients per day, the dentist needs to examine 50 - 32 = 18 patients in the afternoon.

19. Matthew needs to leave home at 6:35 a.m. to arrive at the hospital by 7 a.m. He needs to walk inside from the parking deck for 10 minutes and allot an extra 15 minutes for unexpected traffic delays.

20. The total cost of the co-pay, prescription, and eyeglasses is $25 + $52 + $186 = $263. Therefore, you have $300 - $263 = $37 left to spend from your flex card.
