Jamie has a job paying $25,000 and expects to receive a $1000 raise each year. Wei has a job paying $19,000 a year and expects a $1500 raise each year. For what span of time is Jamie making more money than Wei?
Answer provided by our tutors
let 'x' represent the number of years in which Jamie makes more money that Wei, x is integer
25000 + 1000x > 19000 + 1500x
by solving we find
x < 12
click here to see the step by step solution of the inequality:
since x is integer we conclude that for 11 years Jamie will make money that Wei.
after 12 years they will take same salary since:
25000 + 1000*12 = 19000 + 1500*12.
