To determine how much money Elenore will have in total after saving for \( d \) days, we start with the amount she already has and add her savings over those \( d \) days.
Elenore initially has $75, and she saves $7 per day. Therefore, after saving for \( d \) days, the total amount of money Elenore has can be represented by the following equation:
\[ \text{Total amount} = 75 + 7d \]
Where:
- \( 75 \) is the initial amount of money Elenore has,
- \( 7d \) is the total amount she saves after \( d \) days.
Thus, the equation representing how much money Elenore will have in total after saving for \( d \) days is:
\[ \text{Total amount} = 75 + 7d \]
