Solve the problem.Each ounce of a sweetened yogurt contains 30 calories, while each ounce of a "light" version of the same yogurt contains 4 calories. Write a formula that gives the number of calories C in x ounces of sweetened yogurt. Write a formula that gives the number of calories C in y ounces of "light" yogurt. If a person eats a 10-ounce container of "light" yogurt rather than a 10-ounce container of sweetened yogurt, what is the calorie difference?
A. C = 30 + x; C = 4 + y; 340
B. C = 30 ÷ x; C = 4 ÷ y; 34
C. C = 30x; C = 4y; 520
D. C = 30x; C = 4y; 260
