Answer 1

`h = 316`

Step-by-step explanation:

Given

`Skateboard = 167`

`Savings = 88`

`Earnings = 0.25/hour`

Required

Determine the number of hours he needs to work

From the given parameters, we understand that:

His savings + Total Earnings = Skateboard (cost)

His total earnings in h hours is: 0.25h

So, the above expression can be represented (mathematically) as:

`88 + 0.25h = 167`

Collect Like Terms

`0.25h = 167 - 88`

`0.25h = 79`

Make h the subject

`h = (79)/(0.25)`

`h = 316`

He needs to work for 316 hours
