Question

Diego's parents gave him a fish tank containing 20 goldfish. Each month, Diego purchases 3 goldfish to add to his fish tank.

Which inequality can be used to find m, the number of months after receiving his fish tank, when Diego will have more than 35 goldfish in his fish tank?


3m+20>35


20m+3>35


3m+20<35


20m+3<35

Answer 1

3m+20>35

if you get 3 fish per month (m) then that would be 3m plus the 20 you already have, so 3m+20 but you also want more than 35. sorry if that confusing

Answer 2

3m+20>35

Explanation:

M stands for each month. Every month Diego gets three more goldfish. Since he already has 20 goldfish, it would take at least six months to have more than 35 goldfish.
