You decide to save up for a vacation to Europe by throwing all of your loose change into a large coffee can. After a few months, you discover that the jar is 4 inches full and contains $448.

Determine the average rate of change in $/inch (Dollars per inch), for the coffee can from when it was empty (0 inches) to when it was 4 inches deep.
The average rate of change from 0 to 4 inches is:

A. $112/inch
B. $56/inch
C. $224/inch
D. $448/inch

Answer 1

The average rate of change in $/inch for the coffee can from when it was empty to when it was 4 inches deep is $112/inch.

Step-by-step explanation:

To find the average rate of change in $/inch for the coffee can, we need to determine the change in dollars and the change in inches. The change in dollars is $448 - $0 = $448, and the change in inches is 4 - 0 = 4. Therefore, the average rate of change is $448 / 4 = $112/inch (A. $112/inch).
