To find out how much money Emma had before she bought the salad and drink, we first need to calculate the total amount she spent on the salad and drink.
- Cost of the salad: $4.75
- Cost of the drink: $1.65
Now, add these two amounts together to find the total spent:
\[ 4.75 + 1.65 = 6.40 \]
Now, we know that after buying the salad and drink, Emma had $18.35 left. To find out how much money she had before the purchase, we need to add the total spent to the amount she has left:
\[ \text{Amount before purchase} = \text{Amount left} + \text{Total spent} \] \[ = 18.35 + 6.40 = 24.75 \]
So, Emma had $24.75 before she bought the salad and drink.
The correct answer is $24.75.
