Giselle bought a dress for $35 and three t-shirts. She used a coupon for $2.50 off each t-shirt. The total cost can be modeled by the expression 35 + 3(n - 2.5). What does the expression n - 2.50 represent?

• The cost of the dress minus the coupon amount.

• The total cost of 3 T-shirts minus the coupon amount.

• The cost of each T-shirt minus the coupon amount.

• Total purchase cost minus the coupon amount.
