Question

The restaurant sold coffee and tea during the breakfast shift. The number of cups of tea they sold was 6 more than 1/3 of the number of cups of coffee sold. If the total cups of coffee and tea sold was 70, how many cups of each were sold?

Answer 1

cups of tea = 22

cups of coffee = 48

Explanation:

c = coffee

t (tea) = 6 + 1/3c

t + c = 70

c + 6 + 1/3c = 70

4/3c + 6 = 70

4/3c = 64

4c = 192

c = 48

t = 70 - 48 = 22
