The Frosty Chalet hired Sa’Breia and Kaylyn for their Bradford store. Sa’Breia is the manager. Kaylyn is the cashier. In their first year, Sa’Breia will be paid $15 per hour, and Kaylyn will be paid $7.50 per hour. They have been told that after every year with the company, they will each be given a raise of $2 per hour. Is the relationship between Sa’Breia’s pay and Kaylyn’s pay rate proportional?
