Question

Hank is mowing lawns to earn enough to buy a $1400 computer. After 4 weeks, he has earned $340. What is the least number of full weeks he must work to be able to purchase his computer? Your answer should be a whole number.

Answer 1

12-13 weeks

Explanation:

1 week of work is $85

$1400 - $340 = $1060

$1060 / $85 = 12.47

round it up and its 13 (or not then its 12)

normally you would round down, but i think it would make more sense to round up in this situation
