Answer:
D
Explanation:
Multiply each of the prices by how many platters of steaks they ordered.
12.95x3=38.85
9.95x4=39.8
15.95x3=47.85
Multiply those answers by 16% (.16)
39.8x.16=6.368
38.85x.16=6.216
47.85x.16=7.656
Add those answers to the first answers
39.8+6.368=46.168
38.85+6.216=45.066
47.85+7.656=55.506
Add all of those answers together
46.168+45.066+55.506=146.74
