To find the total price when purchasing two medium one-topping pizzas under the given incentive, we can use the second option provided in the incentive:
- Cost per pizza when buying two: $6.49 each
- Total cost for two pizzas: 2 × $6.49 = $12.98
Thus, the total price for two medium one-topping pizzas when purchased with the incentive is $12.98.
The correct response is $12.98.
