The correct answer is 34.375. Hope this helps.
Tony will get $8.26 back.
Here's why:
First, let's take $1.85 away from $13.59, because he has a coupon. That leaves us with $11.74
Second, do $20 - $11.74 to get your answer, $8.26
Step-by-step explanation:
Given
w(x) = - 3x - 4
Now
w(7) = - 3 * 7 - 4
= - 21 - 4
= - 25
Hope it will help :)❤
