Question

The cost c in dollars to rent a surfboard is proportional to the number of hours H it cost you $30 to rent a surfboard for five hours this situation is c equals

Answer 1

c = 6H

Explanation:

This is a question showing that there is a direct variation between the cost, c, and hours, H.

So that;

c ∝ H

∝ is the proportionality sign

c = kH

where k is a constant of proportionality.

Thus, given that c = $30 and H = 5 hours, then;

30 = k x 5

30 = 5k

Divide both sides by 5 to have;

k =
`(30)/(5)`

k = 6

For this situation, since k = 6; then,

c = 6H
