Question

Graham volunteers each Saturday at a veterinarian's office.

He spends 3 hours cleaning.
He walks dogs for 15 minutes (0.25 hours) each.
• He walks 1 dog at a time.
He volunteers no more than a total of 5 hours each Saturday.
The inequality 3+0.25x ≤5 describes the situation, where x represents the number of dogs he walks. Which of the following is a
reasonable solution to this inequality?
A. 7
B. 11
C. 9
D. -5

Answer 1

A

This because you hqve to eak a number of dogs so its not negative. If you multiply 0.25 by 9 and 11 they will be larger than teo because you have already done 3 hours. 7 will be less than 5 all combines but not in the negatives.
