Question

3.

Deborah decided to mow lawns to earn the $280
she needs for a school orchestra trip. If she earns
$18 per lawn, what is the minimum number of
lawns she needs to mow to earn the money for the
trip?
A. 15
B. 16
C. 18
D. 20

Answer 1

16

Explanation:

Because 15 times 18 is 270. But 18 times 16 is 288.

So she already achieved the money earned with the smallest amount over of what she wanted.
