Judy has $100 and Elenore has $75. Judy is saving $5 per day and Elenore is saving $7 per day. (4 points)

What equation would be used to find out how many days it will take for Judy and Elenore to have the same amount of money saved?

1 answer

Let's denote the number of days it will take for Judy and Elenore to have the same amount of money saved as "d."

The amount of money Judy will have saved after "d" days can be represented as 100 + 5d.

Similarly, the amount of money Elenore will have saved after "d" days can be represented as 75 + 7d.

To find out how many days it will take for them to have the same amount of money saved, we need to solve the equation:

100 + 5d = 75 + 7d
