Judy has $100 and Elenore has $75. Judy is saving $5 per day and Elenore is saving $7 per day.

What equation represents how much money Elenore will have in total after saving for d days?

1 answer

To represent how much money Elenore will have in total after saving for \( d \) days, you can start with the amount of money she currently has and add the amount she saves over \( d \) days.

Elenore currently has $75 and saves $7 for each day, which means after \( d \) days, she will have saved \( 7d \).

Thus, the equation representing how much money Elenore will have in total after saving for \( d \) days is:

\[ E(d) = 75 + 7d \]

Where \( E(d) \) is the total amount of money Elenore has after \( d \) days.
