The equation to represent how much money Elenore will have in total after saving for d days is y = 75d + 7.

The equation to find out how many days it will take for Judy and Elenore to have the same amount of money saved is 100d + 5 = 75d + 7.

After the number of days it took for both to have the same amount of money saved, they would each have $X.
Judy has $100 and Elenore has $75. Judy is saving $5 per day and Elenore is saving $7 per day. (4 points)

What equation represents how much money Elenore will have in total after saving for d days? Respond area 2: y = 100d + 5, y = 5d + 100, y = 5d + 75, y = 7d + 100, y = 100d + 75, y = 75d + 7, y = 7d + 75

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?
7d + 5d = 100 + 75
100d + 5 = 75d + 7
5d + 100 = 7d + 75

After the number of days it took both to have the same amount of money saved, how much money do they have each?
$15
$162.50
$325
$275
$175
The equation that represents how much money Elenore will have in total after saving for d days is y = 75d + 7.

To find out how many days it will take for Judy and Elenore to have the same amount of money saved, you would use the equation 100d + 5 = 75d + 7.

After the number of days it took for both to have the same amount of money saved, they would each have $15.
are you sure??
Apologies for any confusion caused. To find out how many days it will take for Judy and Elenore to have the same amount of money saved, we can set their total savings equal to each other:

100d + 5 = 75d + 7.

Subtracting 75d from both sides:

25d + 5 = 7.

Subtracting 5 from both sides:

25d = 2.

Dividing both sides by 25:

d = 2/25.

So it will take approximately 0.08 days for Judy and Elenore to have the same amount of money saved. Since they cannot have a fraction of a day, we can round up to 1 day.

After 1 day, Judy will have:

100(1) + 5 = 105 dollars.

After 1 day, Elenore will have:

75(1) + 7 = 82 dollars.

Apologies for the mistake in the previous response.
