Correct question is;
Kim ordered a pizza. He has a $1.00 coupon which will get applied after a weekday discount of 15%. Let the X be the original cost of the pizza, C(x) = the cost with the coupon discount applied, and D(x) = the cost with the weekday discount applied.
Which expression gives the cost for Kim’s pizza?
A) C(x) + D(x)
B) D(C(x))
C) C(D(x))
D) C(x) × D(x)
Answer:
Option C: C(D(x))
Explanation:
We are given that;
C(x) = the cost with the coupon discount applied
D(x) = the cost with the weekday discount applied.
Since there is a weekday discount, it means the cost for Kim's pizza will be a function of the discount.
This means that the cost will be C as a function of (D(x)). This can be written as; C(D(x))
