1. The equation representing how much money Judy will have in total after saving for d days is:
Judy's total money = $100 + ($5 × d)
2. The equation representing how much money Elenore will have in total after saving for d days is:
Elenore's total money = $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 both to have the same amount of money saved, they will have the same amount of money.
Judy has $100 and Elenore has $75. Judy is saving $5 per day and Elenore is saving $7 per day.
