use the graph below, which shows the minimum wages in the united states (in dollars) from 1950 through 2015
a. 2000 to 2015
b.
1985->3.4
2000->5.1
change=5.1-3.4=1.7
percentage=change/2000wage
percentage=1.7/3.4=0.5=50%
do same for percent increase in minimum wage from 2000 to 2015
2000->5.1
2015->7.1
change=7.1-5.1=2
percentage=2/5.1=0.3921568627451= 39.22%
c.
2015->7.1
percentage=0.3922
prediction:
minimum wage= minimum wage in 2015 +(percent of increase(minimum wage in 2015)
7.1+7.1*0.3922=9.88462=9.9
predicted amount =9.9
the minimum wage in 2030 is 9.9
d.
No, the prediction is too high because it is likely that the percent increased.
