Answer:
Alexa pays $13.50
Step-by-step explanation:
1. find 40% of each item cost
- ($5 = 100%) /5 = ($1 = 20%) *2 = $2 = 40%
- ($15 = 100%) /5 = ($3 = 20%) *2 = $6 = 40%
- ($2.50 = 100%) /5 = ($0.50 = 20%) *2 = $1 = 40%
2. find cost of each item
- $5 - $2 = $3
- $15 - $6 = $9
- $2.50 - $1 = $1.50
3. find total cost
