$128.40

$120
$111.60
280

$128.40

Step-by-step explanation:

1. Find the cost after the discount.

Multiply the original cost by the discount percentage. This is the amount that was taken off of the original price.

$200 x 40% = $80

Subtract the discount from the original price.

$200 - $80 = $120.

2. Calculate the tax.

Tax is 7% of the final cost.  Multiply the final cost by the tax rate. This determines how much tax was added.

$120 x 7% = $8.40

Add the tax amount to the discounted price.

$120 + $8.40 = $128.40

The final cost is $128.40.
