Answer:
Regular price of 1 pizza = $15 {Assuming discount coupon = $22.5}
Step-by-step explanation:
Let regular non discounted price of 7 pizzas be x
x - 22.5 = 82.5
x = 82.5 + 22.5
x = 105 (Regular Non discounted price of 7 pizzas)
Regular Price of 7 pizzas = 105
Regular price of 1 pizza = 105 / 7 = 15
Since the sides are congruent so are the angles (SSS) so 3x+3x+3x=180 because all the angles in a triangle add up to 180 degrees
9x=180
X=20
So the answer is x =20
