Question

A gorilla needs to eat at least 40 pounds of food each day. The zoo feeds the gorilla using canisters that contain 4 pounds of food. The gorilla

has already consumed 28 pounds of food. How many more canisters z of food does the gorilla need to ear? Write your answer as an inequality.

Answer 1

4z+ 28 ≥ 40

At least would be present as using ≥ or greater than or equal to symbol.

So far the gorilla has consumed 28 pounds of food and each can contains 4 pounds of food.

So: 28 pounds of food/ 4 pounds of food per can= 7 cans consumed

40 pounds needed - 28 pounds consumed= 12 pounds left

12 lbs/ 4 lbs per can= 3 cans left for the gorilla to exceed its goal

Hopefully this helps! :)
