Question

In 1991, the federal minimum wage rate was $4.25 per hour. In 1997, it was increased to $5.15. Find the annual rate of change in the federal minimum wage rate from 1991 to 1997

Answer 1

1991 = $4.25
1997 = $5.15
1hour = 60min
First you will have to multiply:
4.25 * 60 = 225
5.15 * 60 = 309
Then you subtract the answers you got together
309 - 225 = 84
So the the rate of change increases by 84!!
Hope This Helps!!
