Algebra EOC Questions Unit 8: Interpreting Data

A parking garage charges an initial fee of $7.00 for up to 2 hours of parking, and an hourly rate for each additional hour. The table below outlines the prices for up to 5 hours of parking. Which of the following linear equation(s) can be used to find x, the hourly parking rate after the initial fee?

• 7.00 + x = 20.50

• 11.50 + 2x = 20.50

• 7 + 4.50x = 16.00

• 3x + 7.00 = 20.50

Based on the information provided, which statement explains why his solution is incorrect?

• He forgot to multiply x by 2 in Step 1.

• He added x to both sides of the equation in Step 2 instead of subtracting x.

• He added 1 on both sides of the equation in Step 3 instead of subtracting 1

• He multiplied by the reciprocal of 3 to get x = 2 in Step 4.
