Answer:
The price of the 1975 golf ball in 2005 is $0.55
Explanation:
In this question, we are asked to calculate the price of a golf ball in the year 2005 which was bought in the year 1975.
Before we begin to answer, we have been seeing CPI, what could this mean?
The term CPI stands for consumer price index. It refers simply to the change in price of a particular goods or services over a specific period of time.
Now, we mathematically propose a solution to the problem as follows;
We identify the following;
CPI in 1975 = 52.3
CPI in 2005 = 191.3
We now calculate the CPI change between the years. This can be done by dividing the CPI in the year 1975 by the CPI in the year 2005. Mathematically;
CPI change between years = CPI IN 1975/ CPI in 2005
= 52.3/191.3
= 0.273
Now, we proceed to calculate the price of the 1975 ball in 2005.
Mathematically;
A 1975 golf ball’s cost in 2005 = CPI change * price of golf ball in 2005
= 0.273 * 2
= $0.55
