Question

Sara borrows

$
81
$81 from her mother to buy tickets to a concert. If Sara decreases her debt by
$
4.50
$4.50 each week, how many weeks will it take her to pay off the whole amount she owes her mother?

Answer 1

It will take 18 weeks

Explanation:

Here, we are told that she owes a total of $81 which decreases at a rate of $4.50 per week

The number of weeks it will take to finish paying the debt will be the amount owed divided by the payment per week

Mathematically that is 81/4.5 = 18
