Sue has $540 she plans to add $12 each week to this amount how many weeks will it take for her total to reach at least $630 write an inequality to represent this amount
Let's call the unknown variable "w" for the number of weeks. We can represent the total amount of money Sue will have after "w" weeks as $540 + $12w.
To represent the inequality where Sue's total reaches at least $630, we can write:
$540 + $12w ≥ $630
