Use the image to answer the question.
An illustration shows the first quadrant of a coordinate plane titled Temperature Fahrenheit vs Ice Cream Sales.
The x-axis shows temperature in degrees Fahrenheit and ranges from 0 to 85 in increments of 5. The y-axis shows sales in dollars and ranges from 0 to 500 in increments of 50. Eight points are plotted on the graph. The points are plotted at approximate coordinates left parenthesis 0 comma 100 right parenthesis, left parenthesis 50 comma 180 right parenthesis, left parenthesis 55 comma 210 right parenthesis, left parenthesis 60 comma 230 right parenthesis, left parenthesis 65 comma 350 right parenthesis, left parenthesis 70 comma 70 right parenthesis, left parenthesis 70 comma 375 right parenthesis, and left parenthesis 80 comma 500 right parenthesis. An upward slanting line starts at left parenthesis 0 comma 40 right parenthesis and continues to left parenthesis 65 comma 325 right parenthesis.
Market data are gathered for ice cream sales based on the temperature in Fahrenheit. Interpret the slope and y-intercept (0,38)
of the linear model, using the ordered pair (65,325)
. Round the slope to the nearest hundredth.

To find the total number of people who answered the survey about their fruit preference, you sum up all the values in the table:
7th graders: 44 + 120 = 164
8th graders: 35 + 46 = 81
Totals: 72 + 71 = 143
Therefore, the total number of people who answered the survey is 164 (7th graders) + 81 (8th graders) + 143 (Totals) = 388.
