Problem 12
The value of money is affected by the inflation rate-the higher the inflation rate, the less valuable money will become over time. The rate of inflation is calculated using the formula below, in which CPI represents the consumer price index, a measure of the average of a typical basket of consumer goods and services (where goods and services are weighted relative to how often they are purchased by a normal consumer): \(\frac{\text { This Year's CPI - Last Year's CPI }}{\text { Last Year's CPI }} \times 100\) The current rate of inflation would definitely be zero if the CPI a year ago equaled which of the following? (A) The CPI a year from now (B) This year's CPI (C) Zero (D) 100

(B) It will shift up 3 units and shift to the right 2 units. (C) It will shift up 2 units and shift to the left 3 units. (D) It will shift down 3 units and shift to the right 2 units.

Problem 14
A convenience store has a "change bowl" on its counter in which there can be 5-cent nickels and/or 1 -cent pennies. The store manager insists that whenever there is a dollar (100 cents) or more in the bowl, some change must be removed.
