8. T-Shirts & More Print Shop will print any image on a coffee mug for a cost of $2 per mug and a one-time charge of $12 to set up the mug
design. What is the equation for this situation?

T-Shirts $ More Shop: Final cost = 2m + 12

m = mug

You Say It, We Print It: Final Cost = 5m

If you buy 5 mugs from both place:

2 * 5 = 10

10 + 12 = 22

$22 for T-Shirts & More

5 * 5 = $25

$25 from You Say It, We Print It

D. T-Shirts & More is the better buy if you buy more than 4 mugs.

is only a line? i think so
