The number of deposits that she has to make in order to reach her goal of saving $475 is 21 weeks.
The equation that represents the total amount Amelia can save is:
Total amount saved ≥ initial deposits + (weekly deposits x number of weeks)
$475 ≥ $60 + $20x
In order to determine the value of x, take the following steps:
Combine similar terms
$475 - $60 ≥ $20x
$415 ≥20x
Divide both sides by 20
x ≥ 20.75
x ≥ 21 weeks
