Question

A clothing store offers customers a holiday sale of 20% off the price of x items. A customer then has an additional 15% off coupon that can be used when checking out. Which of the following functions represents the final price P(x) of the items purchased?
P(x) = 0.68x
P(x) = 0.35x
P(x) = 0.05x
P(x) = 0.03x

Answer 1

Finding the equivalent multiplier, it is found that the function for the final price is:

P(x) = 0.68x.

-------------------------------------------

• There is a holiday sale of 20% off the price of x, thus 0.8x is paid, as 1 - 0.2 = 0.8.

• Additionally, there is a coupon of 15% off, thus, 0.85 of 0.8x is paid.
• The equivalent multiplier is:

$0.85(0.8) = 0.68$

• Thus, the function for the final price is:

$P(x) = 0.68x$
