Answer:
To find out what percent of your grocery bill you spent on milk, you can use the following formula:
Percentage spent on milk= (cost of milk/total grocery bill)X100
In this case:
- Cost of milk = 3 gallons × $2.19 per gallon = $6.57
- Total grocery bill = $52.56
Now, calculate the percentage spent on milk:
\[ \text{Percentage spent on milk} = \left( \frac{6.57}{52.56} \right) \times 100 \]
\[ \text{Percentage spent on milk} = \left( \frac{6.57}{52.56} \right) \times 100 \approx 12.50\% \]
So, you spent approximately 12.50% of your grocery bill on milk.
