Question

You are a contractor and charge $90 for a site visit plus an additional $24 per hour for each hour you spend working at the site. Write and solve an equation to determine how many total hours you have to work to earn $810 working at two separate work sites. Let the number of hours you work be y.

Answer 1

x=29.66hrs

Explanation:

Firstly, we can model the equation for the total cost as

Let y be the total cost

Let x be the number of hours

Y=98+24x

Also, given that you have earned $810

We can substitute Y=810 and solve for x

810=98+24x

810-98=24x

712=24x

Dividing both sides by 24

712/24=x

x=29.66hrs
