    She ordered 6 large pizzas. Luckily, she had a coupon for 3 off each pizza. If the bill came to 38.94, what was the price for a large pizza?

    Determine additional amount the pizzas would have cost without the coupon
    6 pizzas * 3 per pizza = 18

    Add 18 to our discount price of 38.94
    Full price for 6 large pizzas = 38.94 + 18
    Full price for 6 large pizzas = 56.94

    Let x = full price per pizza before the discount. Set up our equation:
    6x = 56.94

    Divide each side by 6
    x = $9.49
