Answer:

76 ice cream cones

Step-by-step 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
