Question

Cole earns $12.50 per hour and will receive a $0.75 per hour raise every year.Adam earns $10.50 per hour and will receive a $2 per hour raise every other year.The chart shows the expected hourly pay rates for Cole and Adam for the first six years. Assuming the pattern continues, which hourly pay rate will each earn in the year when they are making the same amount per hour?

Answer 1

Answer:

They will have the same amount per hour after 8 years

Explanation:

For Cole, the increase is $0.75 yearly

For Adam, the increase is $2 every two years

The equation for Cole is:

12.50 + 0.75x

Where x is the number of years

The equation for Adam is:

10.50 + 2x/2

They are of the same pay rate when

12.50 + 0.75x = 10.50 + x

Solving for x, we have:

x - 0.75x = 12.50 - 10.50

0.25x = 2

x = 2/0.25

= 8

They will have the same amount per hour after 8 years
