Answer:
The more 'chocolatey' chocolate milk is the one prepared by Nell's mom.
Explanation:
This problem can be solved by establishing the ratio of chocolate syrup for one ounce of milk in each beverage.
For mom's chocolate milk:
![(30mL)/(2ounces) = 15(mL)/(ounce)](https://img.qammunity.org/2019/formulas/mathematics/high-school/u8r8qodjfjwyswwvb4p105f3j9epfoik21.png)
For dad's chocolate milk:
![(65mL)/(5ounces) = 13(mL)/(ounce)](https://img.qammunity.org/2019/formulas/mathematics/high-school/48h1aoljhxqy0puf7ohl86aujtb33kmhdy.png)
We know that:
15 > 13
So we can conclude that mom's chocolate milk is more 'chocolatey'.
