Answer 1

The approximate average rate of change between weeks 1 and 6 is $9.20.

Step-by-step explanation:

The approximate average rate of change between weeks 1 and 6 can be found by calculating the slope of the line passing through the points (1, 17) and (6, 63).

To calculate the slope, we can use the formula:

m = (y2 - y1) / (x2 - x1)

Substituting the values, we get:

m = (63 - 17) / (6 - 1)

Simplifying the equation, we get:

m = 46 / 5

Thus, the approximate average rate of change between weeks 1 and 6 is $9.20.
