Answer: Don has = 5+3x
Lisa has = 20+2x
Step-by-step explanation:
Let x be the number of days.
Given: Don starts with $5 and earns $3 per day. Lisa has $20 and spends $2 per day.
Total money = Amount at the staring + (per day earning ) x (Number of days)
Don has = 5+3x
Lisa has = 20+2x
The required equation to represent how much money Don has and how much money Lisa has:
Don has = 5+3x
Lisa has = 20+2x
