Question

The cost, c, of renting a bicycle and a helmet for h hours is given by the formula c=7.50h+3 Which equation is equivalent to this formula when solved for h?

Answer 1

`h = (c - 3)/(7.50)`

Explanation:

We need to make h subject of the formula

`c - 3 = 7.50h\\So, 7.50h = c - 3`

Divide both sides by 7.50

`(7.50h)/(7.50)=(c-3)/(7.50) \\\\h = (c - 3)/(7.50)`
