Uncle Sam says Hey charges $65 per hour with a one time fee of $425 for accounting services. Write and solve an equation to determine how many hours each company have to work for their costs to be equal?

Respuesta :

Let ‘n’ be the no. Of hours:

85n+305 = 65n+425
85n = 65n+425-305
85n = 65n+120
85n-65n = 120
20n = 120
n = 120/20 = 6 hours

Therefore, Each company has to work 6 hours for their cost to be equal.
