In an effort to eat healthier, Bridget is tracking her food intake by using an application on her phone. She records what she eats, and then the application indicates how many calories she has consumed. One Monday, Bridget eats 10 medium strawberries and 8 vanilla wafer cookies as an
after-school snack. The caloric intake from these items is 192 calories. The next day, she eats 20 medium strawberries and 1 vanilla wafer cookie as an after-school snack. The caloric intake from these items is 99 calories.

a. Write a system of equations for this problem situation. Let S represent the number of calories in one strawberry and let W represent the number of calories in one vanilla wafer cookie.

The equation represents the calories Bridget ate on Monday and the equation represents the calories she ate the next day.

b. Solve the system of equations using the substitution method. Check your work.

The number of calories in each strawberry is
And the number of calories in each vanilla wafer cookie is . The solution is .
