Matteo earns a yearly salary of $40,000. Rico earns a yearly salary of $51,000. Mateo will receive a salary increase of $3,500 per year, and Rico will receive a salary increase of $2,800 per year.
Which equation can be used to find n, the number of years it will take Mateo to earn the same salary as Rice?
40.000n + 3,500n = 51,000n + 2,800n
40.000 + 3.500n = 51,000n + 2,800
40.000 - 3,500n = 51,000+ 2.800n
40.000n + 3.500 = 51,000n + 2,800
