.The equations below show Felicia's benefit of consuming n cups of tea and of consuming m cups of coffee, and tea and coffee are perfectly divisible and can be consumed in any arbitrary quantity (say, 1.25 cups).

Total benefit of tea: T B(n) = 240n 10n 2

Average benefit of tea: AB(n) = 240 10n

Marginal benefit of tea: MB(n) = 240 20n

Total benefit of coffee: T B(m) = 156m 5m2

Average benefit of coffee: AB(m) = 156 5m

Marginal benefitof coffee: MB(m) = 156 10m

Suppose Felicia can only drink 6 cups in total. Felicia would consume [ Answer04A = 4.80 ] cups of tea and [ Answer04B = 1.20 ] cups of coffee.

I would like to know how the ans are calculated.
