Final answer:
After subtracting his movie, arcade, and comic book store expenses from the $46.00 he made, Justin has $7.98 remaining.
Step-by-step explanation:
To calculate how much money Justin has left after his expenses, we need to subtract the amounts he spent at the movies, the arcade, and the comic book store from the total amount he made from mowing lawns.
Here are the steps we follow:
- Start with the total amount Justin made: $46.00.
- Subtract the amount spent at the movies: $46.00 - $16.54 = $29.46.
- Subtract the amount spent at the arcade: $29.46 - $8.50 = $20.96.
- Subtract the amount spent at the comic book store: $20.96 - $12.98 = $7.98.
Therefore, after his expenses, Justin has $7.98 left.
