Question

A bowl contains x cups of milk. Mrs. Medina used 2.15 cups for her cereal. The bowl now contains 1.30 cups of milk. How much milk was in the bowl before Mrs. Medina needed some for her cereal?

0.85 cups

3.45 cups

1.30 cups

2.15 cups​

Answer 1

3.45 cups

Step-by-step explanation

X is the milk in the bowl before it was used

x-2.15=1.30

Move the -2.15 to the right side of the equation. When you move it to the opposite side the sign changes.

x=1.30+2.15

Now just add 1.30 and 2.15

x=3.45
