4 glasses of milk and 2 snack bars have a total of 86 carbohydrates (carbs), and 2 glasses of milk and 3 snack bars have a total of 69 carbs. Determine how many carbs are in one glass of milk and in one snack bar.

There are 15 carbs in one glass of milk and 13 carbs in one snack bar.

Step-by-step explanation:

Let m be the number of carbohydrates in one glass of milk and

Let s be the number of carbohydrates in one snack bar

Then according to given information

The system of equations will be:

Multiplying equation 2 by 2 and subtracting from equation 1

Subtracting from equation 1

Putting s=13 in equation 1

Hence,

There are 15 carbs in one glass of milk and 13 carbs in one snack bar.
