Answer 1

Answer: Don has = 5+3x

Lisa has = 20+2x

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
