A phone company charges a sign-up fee of $3.50, plus $x for every hour the phone is used. If Brian talked on the phone for 12 hours and paid a total of $75.50, which of the following equations can be used to find, x, the hourly rate of the phone plan?

• 3.50 + x = 75.50 

• 3.50 - x = 75.50 

• 75.50 + 12x = 3.50 

• 3.50 + 12x = 75.50

• 3.5

• 4

• 4.5

• 5

Answer explanation

To find the missing value of x, notice the pattern that f(x) increases by 3 each time x increases by 1. Therefore, when f(x) = 10, x must be 4.
