Answer: The graph of the two equations is "A coordinate plane is shown with two lines graphed. y = −x − 1
Step-by-step explanation:
X = number of dimes
y = number of quarters
---
10x + 25y = 2565
y = x + 20
---
put the system of linear equations into standard form
---
10x + 25y = 2565
x - y = -20
---
copy and paste the above standard form linear equations in to this solver:

solution:
x = 59
y = 79
<h2>
Hello!</h2>
The answer is:
The second option,
b.)
<h2>
Why?</h2>
We are given the functions E(x) and K(x), since they both are function of the same variable, we need to add them in order to find the correct option.
From the statement we know the functions:
and
So, adding the functions we have:
Hence, the answer is the second option,
b.)
Have a nice day!
The expression would be 32+3x where x represents the cost of each shirt. If the shirts were $9 each max would have spent $59
