Let's denote the number of days it took for both Judy and Elenore to have the same amount of money saved as "x".
Judy saves $5 per day, so after x days, she will have saved 5*x dollars.
Elenore saves $7 per day, so after x days, she will have saved 7*x dollars.
Given that Judy starts with $100 and Elenore starts with $75, we can set up the equation 100 + 5x = 75 + 7x.
Subtracting 5x from both sides of the equation, we have 100 = 75 + 2x.
Subtracting 75 from both sides of the equation, we have 25 = 2x.
Dividing both sides of the equation by 2, we have x = 12.5.
After 12.5 days, both Judy and Elenore will have the same amount of money saved.
Judy will have saved 5*12.5 = $<<5*12.5=62.50>>62.50.
Elenore will have saved 7*12.5 = $<<7*12.5=87.50>>87.50.
Therefore, after 12.5 days, Judy will have $62.50 saved, and Elenore will have $87.50 saved.
Judy has $100 and Elenore has $75. Judy is saving $5 per day and Elenore is saving $7 per day. (4 points)
After the number of days it took both to have the same amount of money saved, how much money do they have each?

are you sure
I apologize for the incorrect response in my previous message. You are right, I made an error in the calculations.
To determine the number of days it takes for Judy and Elenore to have the same amount of money saved, we can set up the equation:
100 + 5x = 75 + 7x,
where x represents the number of days.
Subtracting 5x from both sides, we get:
100 = 75 + 2x.
Subtracting 75 from both sides, we have:
25 = 2x.
Dividing both sides by 2, we find:
x = 12.5.
Therefore, it takes 12.5 days for Judy and Elenore to have the same amount of money saved.
To determine how much money they each have after 12.5 days:
Judy saves $5 per day, so after 12.5 days, she will have saved 5 * 12.5 = $62.50.
Elenore saves $7 per day, so after 12.5 days, she will have saved 7 * 12.5 = $87.50.
Therefore, after 12.5 days, Judy will have $62.50 saved, and Elenore will have $87.50 saved.
