Minimum Wage in the United States

[nycmathguy]

For (a), I say 2000 to 2010 decade.

For (b), the set up is:

5.1/3.4 = x/100

Let x = percent increase in minimum wage from 1985 to 2000.

5.1/7.1 = y/100

Let y = percent increase in minimum wage from 2000 to 2015.

What is the set up for part (c)?

I cannot answer part (d) without knowing my prediction in part (c).

You say?

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.

Very good but is anything I did here right? Don't tell me I got everything wrong. This is depressing.
