Final answer:
The total amount when mixing 1 3/4 cups of milk and 2 1/2 tablespoons of chocolate sauce is 1.90625 cups, which is closest to 2 1/8 cups, although the provided options seem to have an error as none directly match the calculated result.
Step-by-step explanation:
To determine the total amount in cups of a mixture of milk and chocolate sauce, we first need to convert all the quantities to the same unit. We start with 1 3/4 cups of milk. We then add 2 1/2 tablespoons of chocolate sauce. Since there are 16 tablespoons in a cup, we can convert the tablespoons of chocolate sauce into cups by dividing by 16.
So, we convert 2 1/2 tablespoons to cups:
2.5 tbsp × (1 cup / 16 tbsp) = 2.5 / 16 cups = 0.15625 cups.
Now, we add this to the 1 3/4 cups of milk:
1.75 cups + 0.15625 cups = 1.90625 cups.
The closest answer to 1.90625 cups is 1 7/8 cups, which is not one of the provided options. Hence, there seems to be an issue with the provided answer choices, as none of them match the calculation. However, if we were to choose the best approximation from the given options, 2 1/8 cups would be the closest match, despite being a slight overestimate.
