We know some facts:
- x for the original price.
- The store has a coupon for $10 off and a discount of 20%
- C for the price after the coupon is applied.
So from the statement 2, you can realize there are two types of discounts:
- The discount offered by the coupon
- The discount offered by 20%
Since we need to write a function just for the coupon, then we don't include the discount offered as percentage, then we subtract the coupon from the original price:

The sum of any two rational numbers is rational. Both of these numbers are rational, therefore adding them will give us another rational number.
Answer:
D)
Step-by-step explanation:
sec(x) = 1/cos(x)
You know cos(x) = 1 for x=0, so sec(0) = 1.
You also know that sec(x) has vertical asymptotes where cos(x) = 0, at odd multiples of π/2. Only selection D matchest these characteristics.
