Answer:
Number of year Mary’s salary be the same at both = 7 year
Equal salary amount = 46,500
Step-by-step explanation:
Given:
Starting salary in job A = 36,000
Gain per year in job A = 1,500
Starting salary in job B = 29,000
Gain per year in job B = 2,500
Find:
Number of year Mary’s salary be the same at both = ?
Equal salary amount = ?
Computation:
Assume : in x year salary from job A is equal to salary from job B
Salary from job A in x year = 36,000 + 1,500 x .........Eq1
Salary from job B in x year = 29,000 + 2,500 x .........Eq2
From Eq1 and Eq2
36,000 + 1,500 x = 29,000 + 2,500 x
7,000 = 1,000 x
x = 7 Year
Number of year Mary’s salary be the same at both = 7 year
From Eq1....
Equal salary amount = 36,000 + 1,500(7)
Equal salary amount = 36,000 + 10,500
Equal salary amount = 46,500
