Answer:
3 days
Step-by-step explanation:
Let x - be the number of days
Jack: 55 + 4x
Emily: 28 + 13x
To know when they would have the same amount of money, you make the two equations equal to each other.
Hence:
55 + 4x = 28 + 13x
Rearrange:
55 - 28 = 13x - 4x
Simplify
27 = 9x
Divide each side by 9 to make x on its own (this way we would be able to know the number of days when they get the same amount of money)
x = 3 (3 days)
