Answer: $28-$33
Step-by-step explanation: Call the cost per pair x. She buys the first pair full price, so x, then 2 dollars off, so x-2, and 2 dollars off, so x-2, adding them up you get 3x-4= total money spent. Sinze this ranges from 80-95 solve equations and you get 28 and 33 respectively.
Answer: The equation that represents the other equation is
.
The solution of the system is <u>(3,6).</u>
Step-by-step explanation:
Linear equation:
, where m= slope
c = y-intercept.
In the first table, the y-intercept = 5 [ y-intercept = value of y at x=0.
Slope for first table = 
The equation that represents the first table:

So, the equation that represents the other equation is
.
Also, the solution of the system is the common point (x,y) that satisfy both equations in the system.
Here, x=3 and y=6 is the common value in both tables.
So, the solution of the system is <u>(3,6).</u>
