Question

Candice enjoys eating foods high in vitamin C to stay healthy. On Saturday, she ate 4 clementines and 7 kiwis for a total of 732 mg of vitamin C. On Sunday, she ate 8 clementines and 5 kiwis for a total of 708 mg of vitamin C. How much vitamin C is in each fruit?

Answer 1

4c + 7k = 732
8c + 5k = 708

-8c - 14k = -1464
8c + 5k =. 708

-9k = -756

k= 84 mg of vitamin C in kiwis each

4c + 7(84)= 732

4c + 252 = 732

4c = 480

c = 120 mg of vitamin C in clementines each
