Question

Juan is saving for a new laptop and has saved $205 . He is saving $4 a day and needs at least $849 for the laptop he wants . How many weeks will it take him to save for the laptop he wants ?

A. At most 161 weeks
B. At least 161 weeks
C. At least 23 weeks
D. At most 213 weeks

Answer 1

C. At least 23 weeks

Explanation:

First, you can subtract 205 from 849.

849-205=644

He needs 644 more dollars, and he saves $4 every day. So: 644/4=161

He needs 161 days, but the question is asking in weeks, so: 161/7=23

Answer 2

B. At least 161 weeks

Explanation:

849-205=644

644/4=161 or more weeks
