Question

Using the model, approximate the number of ice cream cones sold when it is 85°F. Round your answer to the nearest whole number.

Answer 1

76

Explanation:

y = 1.8(85) - 76.9

y = 153 - 76.9

y = 76.1

and when you round to the nearest whole number,

y = 76

Answer 2

76.1

Explanation:

y = ice cream

z = Tempreature

y = 1.8(85) - 76.9

1.8(85) = 153

153 - 76.9 = 76.1
