To determine how much more Suzi can spend, we first need to calculate her total spending so far and then see how much budget she has left.
Suzi's total budget is $28.
She spent:
- $8 on lunch
- $12 on movie tickets
Total spent so far: \[ 8 + 12 = 20 \]
Now, we subtract her total spending from her budget: \[ 28 - 20 = 8 \]
Suzi can spend an additional $8 without going over her budget.
So, the correct answer is: $8.
