Step-by-step explanation:
To find out how much the milk for one portion costs, we first need to convert the price of milk per gallon to the price per ounce.
Given:
- Price of milk per gallon: $2.48
- One gallon = 128 ounces
Price per ounce of milk:
\[ \text{Price per ounce} = \frac{\text{Price per gallon}}{\text{Number of ounces per gallon}} \]
\[ \text{Price per ounce} = \frac{2.48}{128} \approx 0.019375 \]
Now, we know that one portion of oatmeal requires 4 ounces of milk. So, the cost of the milk for one portion of oatmeal is:
\[ \text{Cost} = \text{Price per ounce} \times \text{Number of ounces} \]
\[ \text{Cost} = 0.019375 \times 4 \approx 0.0775 \]
Rounded to the nearest cent, the cost is $0.08.
So, the answer is:
b. $0.08
