Answer:
$51.90
Step-by-step explanation:
We need to work out the cost of the 3 sweaters, so each sweater's original cost needs to be subtracted by $2.25.
$19.55 x 3 = $58.65 Here, we work out the total cost of the 3 sweaters without the discount.
$2.25 x 3 = $6.75 This is the discount amount for the 3 sweaters in total.
$58.65 - $6.75 = $51.90 We subtract the total original cost by the discount amount to get the answer.
