Answer:
The answer is 6 pizza's
Step-by-step explanation:
It is 6 pizza's because we make the equation 7x+3=45, 7x=42, x=6
So it is 6 pizza's
Robert delivered 6 pizzas because
45 - 3 (the delivery fee) = 42
42/7(cost per pizza) = 6 pizzas delivered
45 - 3 (the delivery fee) = 42
42/7(cost per pizza) = 6 pizzas delivered
