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
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!! :)
