Dylan Best · Answer 1

3200≥1200+600+675 Because, the phone plan only allows at maximum 3200 minutes, meaning that all of the minutes the family has used has to be less than or equal to 3200 minutes (Or 3200 minutes is greater than the amount of minutes used by the Cruz family)

Layla Carlson · Answer 2

father used 1200

each child used 675 (675 * 2) = 1350 min total

mother used >=600

1200 + 1350 = 2550

2550 + 600 = 3150

so minutes used is greater than or equal to 3150 minutes
