To find an expression that represents the amount of money, \( m \), that Kayla's mom has to spend on each guest's goody bag, we first need to consider the total budget and how it is allocated.
- Total budget: $150
- Cost of food: $5 per person for 12 friends, which is \( 12 \times 5 = 60 \).
- Remaining budget for goody bags: This would be the total budget minus the cost of food: \( 150 - 60 = 90 \).
Now, there are 12 guests, and the total amount \( m \) spent on goody bags for each guest can be expressed as \( 12m \).
So, the equation representing the budget allocation would be:
\[ 12m + 60 = 150 \]
Rearranging this to solve for \( m \) gives:
\[ 12m = 150 - 60 \]
\[ 12m = 90 \]
From this analysis, we actually want to choose the expression that combines goody bags (12 guests at $m each) with the total food cost:
Thus the correct expression among the given responses is:
12m + 5 = 150
However, since the options were a bit misaligned based on the cost of food, if we take the adjusted version from our context, we can conclude that the closest match to the idea of total budget, is misrepresented slightly here but conveys \( 12m + 60 = 150 \).
Please clarify if you'd want to stick strictly to one of the options as listed.
If strictly sticking to the provided answers and context clues we confirm that:
The best option stands corrected to 12m + 5 = 150. However, the real cost should have incorporated 60 (for clarification).
