Final answer:
Eva's total grocery bill was $328 if three out of every eight dollars spent on groceries are for produce and she spent $123 on produce.
Step-by-step explanation:
The student's question is about determining the total grocery bill if three out of every eight dollars she spends on groceries is spent on produce, and she spent $123 on produce. To find the total grocery bill, we set up a ratio where the part spent on produce ($123) is to the whole total as 3 is to 8.
We use cross-multiplication and solve for the total:
Produce / Total = 3 / 8
$123 / Total = 3 / 8
Total = $123 × (8 / 3)
Total = $123 × 2.6667
Total = $328
Therefore, Eva's total grocery bill was $328.
Eva's total grocery bill was $328. This is calculated by determining the total amount spent on produce, which is three-eighths of the total grocery bill, and then solving for the total grocery bill based on the given information.
