To determine the expected price of a good in 2000, knowing that in 2015 it cost $ 17.6 and that the consumer price indexes were worth 172.2 in 2000 and 237.017 in 2015, the following calculation must be performed:

237.037 = 17.6

172.2 = X

X = 172.2 x 17.6 / 237.037

X = 3,030.72 / 237.037

X = 12.78

Thus, the expected price of the good in the year 2000 is $ 12.78.

Use substitution to solve the system of equations.

(3.75, 5.5)

(Work is attached )
When using substitution , you substitute with a variable that is already by itself. In this case, the variable “y” is already by itself and equal to x+ 1.75 . you substitute that for the the y in the other equation and solve for the other variable which is “x”. After you solve for x , to find your y value, you have to substitute the x value in for either equation.
