Question

If 1 box of supplies lasts for 5 days, how many boxes are needed for 30 days?

a) 4 boxes
b) 5 boxes
c) 6 boxes
d) 7 boxes

Answer 1

To find out how many boxes are needed for 30 days, we can use the proportion 1 box / 5 days = x boxes / 30 days. Solving for x, we find that 6 boxes are needed.

Step-by-step explanation:

To find out how many boxes are needed for 30 days, we can use a proportion. Since 1 box lasts for 5 days, we can set up the proportion: 1 box / 5 days = x boxes / 30 days. Cross-multiply and solve for x:

1 * 30 = 5 * x

30 = 5x

x = 30 / 5 = 6

Therefore, 6 boxes are needed for 30 days.
