A computer store bought a program at a cost of $10 and sold it at a selling price of $13. Find the percent markup? The percent markup is __%

answer:

c. the third graph

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.
