You are a contractor and charge $65 for a site visit plus an additional $15 per hour for each hour you spend working at the site
Katena32 [7]

Answer:

h = 59 hours

Step-by-step explanation:

Total earnings = fixed charge + variable charge

Fixed charge = $65

Variable charge = $15h

Where, h = number of hours

Total earnings = $950

Total earnings = fixed charge + variable charge

950 = 65 + 15h

Subtract 65 from both sides

950 - 65 = 65 + 15h - 65

885 = 15h

Divide both sides by 15

h = 885 / 15

= 59

h = 59 hours
