To predict the sales in dollars and cents if the temperature is 70 degrees Fahrenheit, we can plug in x = 70 into the equation of the trend line:
y = 6.25x + 30
y = 6.25(70) + 30
y = 437.50 + 30
y = 467.50
Therefore, if the temperature is 70 degrees Fahrenheit, the predicted sales in dollars and cents would be $467.50.
Market data are gathered for ice cream sales,y, based on the temperature in degrees Fahrenheit,x, Using the equation of the trend line y = 6.25x + 30 predict the sales in dollars and cents if the temperature is 70 degreesF
