Gustavo earns 8 dollars per hour plus 10% of his sales. write an equation that models gustavo's total earnings, e, when he works x hours and has a total of y sales in dollars. you do not need to solve the equation.

e = 8x + 0.1y

Step-by-step explanation:

If Gustavo makes no sales at all, he still gets $8 per hour worked (x).  We can model this part with this equation:

e = 8x

But then, if he sells something, he makes extra money.. He makes 10% (0.1) of every sale (y).  So the equation becomes:

e = 8x + 0.1y

or you can express it this way:

e = 8x + y/10

which is the same thing just written differently.

yes
