Question

Katelyn bought a hot dog for $4. She also bought some water bottles for $2 each. Katelyn did not spend more than $15 on the hot dog and the water bottles. Which inequality can be used to find, w, the number of water bottle Katelyn could have bought?

Answer 1

4+2w ≤ 15

Explanation:

Purchases:

1 hot dog for $4

w water bottles at $2 each

4 +2w

She did not spend more than 15

4+2w ≤15

Solving for w

4+2w≤15

Subtract 4 from each side

4-4+2w ≤15-4

2w≤11

Divide by 2

2w/2 ≤ 11/2

w ≤ 5.5

She could buy up to 5 water bottles
