The recipe calls for 1 and 1/4 cups of chopped apples, which is equivalent to 1.25 cups. Since Maria leaves out 1/2 cup of the apples to use later, she puts in:
1.25 cups - 0.5 cups = 0.75 cups of chopped apples in the bowl.
Next, she adds 1/4 cup of vegetable oil to the bowl.
Now, to find the total amount of apples and oil in the bowl, we add the amounts together:
0.75 cups (chopped apples) + 0.25 cups (oil) = 1 cup.
So, the total amount of apples and oil in the bowl is 1 cup.
