1) The equation that represents how much money Judy will have in total after saving for d days is:
Judy's total savings = $100 + $5*d
2) The equation that represents how much money Elenore will have in total after saving for d days is:
Elenore's total savings = $75 + $7*d
3) The equation that would be used to find out how many days it will take for Judy and Elenore to have the same amount of money saved is:
$100 + $5*d = $75 + $7*d
4) After the number of days it took for both to have the same amount of money saved, the total savings for both will be:
$100 + $5*d = $75 + $7*d
Simplifying, we get:
$25 = $2*d
Dividing both sides by 2, we get:
d = 12.5
Therefore, after 12.5 days, both Judy and Elenore will have the same amount of money saved.
Judy will have $100 + $5*12.5 = $162.50
Elenore will have $75 + $7*12.5 = $162.50.
Judy has $100 and Elenore has $75. Judy is saving $5 per day and Elenore is saving $7 per day. (4 points)
