To determine how much more Suzi can spend on the outing, we first need to calculate how much she has already spent.
Suzi has a total budget of $34. She spent:
- $8 on lunch
- $12 on movie tickets
Now, we add these two amounts to find the total she has spent:
\[ \text{Total spent} = 8 + 12 = 20 \]
Next, we subtract the total spent from her budget to find out how much more she has left to spend:
\[ \text{Remaining budget} = 34 - 20 = 14 \]
Thus, Suzi can spend an additional $14 without going over her budget.
