Regents Exam: Algebra I August 2016 (Problem 14 of 37)

The video tutorial explains how to determine the additional hourly parking rate for a parking garage that charges a base rate of $3.50 for up to 2 hours. It describes the process of identifying the correct linear equation to calculate the hourly rate after 2 hours, which is $5.50 per hour. The tutorial walks through the steps of analyzing different linear equations to find the one that accurately represents the rate increase, ultimately identifying the correct equation through substitution and verification.

What is the base rate charged by the parking garage for up to 2 hours?

• $2.50

• $3.50

• $4.50

• $5.50

How much does the parking rate increase per hour after the initial 2 hours?

• $6.00

• $5.50

• $5.00

• $4.50

If the price for 3 hours of parking is $9, what is the additional hourly rate?

• $5.50

• $4.50

• $3.50

• $6.50

Which method is used to determine the correct linear equation for the additional hourly rate?

• Using a calculator

• Guessing the rate

• Asking the parking attendant

• Substituting the known rate into each equation

What is the correct linear equation if the additional hourly rate is $5.50?

• 9 + 3x = 20

• 9 + 2x = 19

• 9 + 5.5x = 25

• 9 + 4x = 21
