Question

The instructions for baking a turkey recommend cooking a 12-pound bird for 30 minutes in a 350 degree oven. The instructions also suggest adding 3 extra minutes of cooking time for each additional pound. The cooking time for a turkey can be calculated using the equation below, where w represents the wieght of the turkey.

If Maria needs to cook her turkey for 45 minutes, how many pounds does Maria's turkey weigh?

Cooking Time = 3(w - 12) + 30

Answer 1

45=3(w-12)+30
SOlve for w
45=3w-36+30
combine like terms
45=3w-6
add 6 to both sides
51=3w
divide each side by 3
w=17lbs
