Jose has saved $75 to take tutoring classes. He must pay a registration fee of $15 and then an additional $6 for each class. Write an equation and solve it to determine the number of classes that Jose can afford.

Given:

Total amount Jose has =  $75

Registration fee = $15

Additional fee = $6 for each class

To find:

Number of classes that Jose can afford.

Solution:

Let x be the number of classes that Jose can afford.

Additional fee for 1 class = $6

Additional fee for x classes = $6x

Total fee = Registration fee + Additional fee for x classes

Divide both sides by 6.

Therefore, the required equation is and the number of classes he can afford is 10.
