To represent the total amount of money Jamari has, we can use the following expression:
- Start with what Jamari already has saved, which is $30.
- For each dog he walks, he earns $8. If \( d \) is the number of dogs he walks, then he earns \( 8d \) for walking those dogs.
Combining these two amounts, the expression for the total amount of money Jamari has is:
\[ \text{Total Money} = 30 + 8d \]
This expression accounts for both his savings and his earnings from walking dogs.
