Mary has been offered two manager jobs. The Olive Garden manager job has a starting salary of $36,000 and a raise of $1500 every year. Chipotle has a starting salary of $29,000 and a raise of $2500 every year. Which equation could be used to determine when the salaries at both jobs would be the same?

• 36,000x + 1,500 = 29,000x + 2,500

• 36,000 - 29,000 = 1,500x + 2,500x

• 36,000 - 1,500x = 29,000 - 2,500x

• 36,000 + 1,500x = 29,000 + 2,500x
