an ice cream truck sells ice cream between 2 p. m. and 10 p. m. each night in the summer. at the end of the night, the driver calculates his profits and makes a graph to analyze the data. what is the average rate of change for the from the 1st hour to the 4th hour? be sure to include the correct units of measurement.

a scatter plot with x axis labeled hour and y axis labeled money earned in dollars per hour with points at 1 comma 54 and 2 comma 58 and 3 comma 64 and 4 comma 78 and 5 comma 96 and 6 comma 126 and 7 comma 99 and 8 comma 75

24 dollars
24 dollars per hour per hour
8 hours
8 dollars per hour per hour

The rate of change is the change in Y over the change in X.

Y is the dollar amount at 4 is is 78 at 1 it is 54,  the change is 78-54 = 24

X is the time the change from 4 to 1 is 3 ( 4-1=3)

The rate of change is 24/3 = 8

The answer is 8 dollars per hour.

Step-by-step explanation:

Given 1 comma 54 and 2 comma 58 and 3 comma 64 and 4 comma 78,

the profits at 1st hour is $54 and at 4th hour is $78.

The average rate of change = profit change /  time change

= $78 - $54 / 4hrs - 1hr

= $24 / 3hrs

= $8/hr or 8 dollars per hour

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
