Answer: A. c = 1.35n + 15
Explanation:
Given: Charge for each job = $15
Additional cost per poster = $ 1.35
Total cost = Charge for each job + (Additional cost per poster) (Number of posters) ...(i)
Varaibles:
c= Tota; cost for n posters.
Substitute all values in (i), we get
![c=15+1.35n](https://img.qammunity.org/2022/formulas/mathematics/college/yyty5byrot0k2cs943y4pyxh9ywmz8d76h.png)
Hence, the required equation : c = 1.35n + 15
Hence, the correct option is A. c = 1.35n + 15.
