Zoey goes to a store an buys an item that costs x dollars. She has a coupon for 15% off, and then a 9% tax is added to the disco
pshichka [43]

Answer:

0.9265x

Step-by-step explanation:

x - 0.15x + 0.09(0.85x)

x is the initial amount, -0.15x is subtracting 15% of the original amount (leaving 0.85x), and 0.09(0.85x) is the 9% tax.

Simplified:

x - 0.15x + 0.09(0.85x)

= 0.85x + 0.0765x

= 0.9265x
