The original price is $21.59
take 19 divide by 0.88 (from 100% - 12%)
When you do 11^7 divided by 11^4 you get:
1331
Answer:
(1, 4)
Step-by-step explanation:


Below are a few points for Equations (1) and (2).}

Equation (1) is the blue line in the graph below.
Equation (2) is the red line.
The two lines cross at the black dot
Your four points are labelled . The one that is closest to the intersection is (1, 4).
The approximate solution to the system of equations is (1, 4).
X=22 because if y=6 and x=10 so 6+4=10 so 18+4=22
