For her phone service, Amy pays a monthly fee of $18, and she pays an additional $0.04 per minute of use. The least she has been charged in a month is $74.24.
What are the possible numbers of minutes she has used her phone in a month?

SnapAndSolve AI · Accepted Answer

To find the possible numbers of minutes Amy has used, we set up the inequality based on the total cost:

18 + 0.04m ≥ 74.24

Subtract 18 from both sides:

0.04m ≥ 56.24

Divide both sides by 0.04:

m ≥ 1406

Therefore, the possible numbers of minutes she has used are 1406 or more.
