Answer 1

C

After 4 weeks he has $470. There are 2 weeks left under the original plan.

Option A: Delay one week and keep saving $125/week, so he saves 3 more weeks:
470 + 3(125) = 470 + 375 = 845 ≥ 750.

Option B: Save $125 + $15 = $140/week for the remaining 2 weeks:
470 + 2(140) = 470 + 280 = 750.

Thus both options allow him to meet the $750 goal.
