Latoya's fish tank has 18 liters of water in it. She plans to add 6 liters per minute until the tank has at least 60 liters. What are the possible numbers of minutes Latoya could add water?

Question

use t for number of minutes

Answer 1

you start with 18 liters and every minute (m) you plan to add 6, the final product will have at least (≥) 60 so the equation would be:

18+6m≥60, 6m≥42, m≥7

so Latoya could add water for 6 minutes or more

Answer 2

18 + 6t ≥ 60

Can you solve for t and answer?
