Final answer:
To compare the rate of pizzas baked per hour for Oven A, divide the total number of pizzas baked by the total number of hours to get the rate of pizzas baked per hour.
Step-by-step explanation:
To compare the rate of pizzas baked per hour for Oven A, we need to calculate the number of pizzas baked per hour.
Given that Oven A can bake 288 pizzas in 21 hours, divide the total number of pizzas baked by the total number of hours:
Rate = Total number of pizzas baked / Total number of hours = 288 / 21 ≈ 13.714 pizzas per hour.
Therefore, Oven A can bake approximately 13.714 pizzas per hour.
