Question

Bryan is making chocolate chip cookies. He has a bag of chocolate chips. He uses 12 of his total amount of chocolate chips in the first batch and 1/4 of his total amount in the second batch. If he used 3 cups of chocolate chips, how many cups of chocolate chips were in the bag to start?

12 cups
15 cups
16 cups
18 cups

Answer 1

To find the total number of cups of chocolate chips in the bag, set up an equation and solve for 'x'.

Step-by-step explanation:

To find the total number of cups of chocolate chips in the bag, we can set up an equation. Let 'x' represent the total amount of chocolate chips in the bag.

In the first batch, Bryan uses 12 cups of chocolate chips, so he is left with (x - 12) cups.

In the second batch, he uses 1/4 of the remaining chocolate chips, which is (1/4) * (x - 12) cups.

Given that he used a total of 3 cups of chocolate chips, we can set up the equation: 12 + (1/4) * (x - 12) = 3.

Solving this equation will give us the value of 'x', which represents the total number of cups of chocolate chips in the bag.
