Mark’s salary starts at $26,000 per year with annual raises of $1500. Jon’s starting salary is $29,300 with annual raises of $950 after how many years will the two men earning the same
marks salary 26000+1500x x=number of years
jon salary 29300+950x x=number of years
we want them to have the same salary so we set the equations equal to each other
26000+1500x=29300+950x subtract 950x from both sides
26000+1500x-950x=29300 subtract 26000 on both sides
1500x-950x=29300-26000 combine like terms
550x=3300 divide by 550 to find x
x=6 in 6 years they earn the same
Let their salary reaches same value after y years.
So we can make following equations,
26000 + 1500 y = 29300 +950 y
550 y = 3300
Thus y = 6
They will earn same after 6 years.
