Dimitri used a coupon that saved him 80 percent, or $27.48. The price of the items before the discount was $34.35.

Explanation

The diagram shows that 20% corresponds to $6.87, so 100% is five times that amount: $6.87 × 5 = $34.35. The remaining 80% is four times $6.87, or $27.48. Therefore, Dimitri saved $27.48 with the coupon, and the items cost $34.35 before the discount, as choice D states.
