Answer:
Option C.
Step-by-step explanation:
It is given that,
Service cost = $10 per month
Free rental DVD = first 3
Rental after first 3 DVD = $2 per month
We need to find the expressions models for the total amount that Tharun pays, in dollars, in a month when he rents d, DVDs where d>3.
Fixed cost = $10
Rental apply after first three DVD. So,
Variable cost = $2(d-3)
Total cost = Fixed cost + Variable cost
Therefore, the required expression is C.
47%= 47/100
I hope it is ok!
