Questions 14-16 Write an equation that can be used to represent the number of cups, C, of hot chocolate drank as a function of degrees, F, Fahrenheit? C = 3600 - 120F Your answer 5 points 14. How many cups would they drink at 5°F? Your answer 15. How many cups would they drink at 25°F? al



Answer :

We know that

• They drink 3,600 cups in a day at 0°F.

,

• The consumption decreases 120 cups each degree.

Since consumption decreases, 120 must be negative.

Also, the constant ratio for change is 120 because that's the variation, this number must be the coefficient of temperature.

Additionally, the initial condition is 3,600 cups, that is, the independent term must be 3,600.-

Therefore, the expression is

[tex]C=3,600-120F[/tex]
