d. 34

Answer:

Option c. 40

Step-by-step explanation:

Let the amount paid over the 8 months be $ 280.00

The discount received per month is $ 5.00

The amount paid each month for 8 months is given by:

[tex]\frac{280}{8} \\= 35[/tex]

However, if he stopped using autopay, he will pay each month:

Amount = $ 35 + $ 5

              = $ 40

Noah would pay $40 each month

The discount Noah received decreased the amount he pays by $5 every month.

Total discount in 8 months = 8 x $5 = $40

If Noah stopped using autopay, he would have to pay the full amount

Without the discount, the total amount Noah would pay in 8 months = amount paid without discount + total discount amount

$280 + $40 = $320

Amount Noah would pay per month = Total amount he pays in 8 months without discount / 8

$320 / 8 = $40
