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
The required equation to represent how much money Don has and how much money Lisa has:
Answer:
y=5/2x
The line needs to go through the points (0,0) and (2,5).
With y=5/2x, there is no y-intercept, so it starts on the origin, (0,0). With the slope 5/2, you would rise 5 (y) from the origin, and run 2 (x), which gives you the point (2,5).
