Question

An art student is trying to determine how many tubes of paint they will need for their mural. If they are using 3 tubes every 4 days, how many tubes would they use in 8 days?

Answer 1

Answer: 6 tubes

Explanation:

Create a simple relationship.

4 days = 3 tubes

8 days = ? tubes

Well, if there is twice as many days, twice as many tubes will be used.

4 days x 2 = 8 days

3 tubes x 2 = 6 tubes
