Question

The model y=1.8x−76.9 y=1.8x−76.9 represents the relationship between the temperature (°F) and the number of ice cream cones sold. 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 ice cream cones

Explanation:

Given the model : y=1.8x−76.9 ;

Which shows the relationship between temperature and number of ice cream cones sold ;

Using the model, the predicted number of ice cream cones sold when temperature is 85°F

Hence, x = 85

Putting x = 85 in the model and solve for y

y = 1.8(85) −76.9

y = 153 - 76.9

y = 76.1

Hence, the number of ice cream cones sold is 76
