Opal made t-shirts. It cost $39 to print one shirt. It costs $75 for 10 shirts. Write an equation to represent the
relationship between the cost and the number of shirts printed. How much
would it cost to produce 8 shirts?

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
