The system of inequalities represents the number of color copies, x, and grayscale copies, y, that julissa can print to meet her goal is;
x + y ≥ 8
x + y ≥ 84x + 2y ≤ 25
<h3>Inequality</h3>
let
- Number of color copies = x
- Number of grayscale copies = y
- Time to print color copies = 4 minutes
- Time to print grayscale copies = 2 minutes
- Total copies = 8
- Total time = 25 minutes
x + y ≥ 8
4x + 2y ≤ 25

Answer:
(8,7)
apologies for a very ugly graph
lmk if you want me to elaborate
Since x and y are directly related, the equation for their comparison will look like
kx = y
where k is your constant. They give you an instance in the problem where x = 27 and y = 81. Plug this into the above equation and solve for k.
kx = y
k (27) = 81
k = 3
Thus, the constant of variation is 3.
In first calculation Miranda was first calculating tax of a 7% of 19$ tennis racket and than she added it to cost of tennis racket. In second calculation she automatically calculated 107% of a price of tennis racket that she will pay at register.
