olya-2409 [2.1K]

Answer:

74%

Step-by-step explanation:

We have been given that the Average cost of a long distance call in the USA was 31 cents per minute in 1978 and 8 cents in 2008.

We will use percent decrease formula to solve our given problem.

$\text{Percent decrease}=\frac{\text{Initial}-\text{Final}}{\text{Initial}}\times 100\%$

$\text{Percent decrease}=\frac{31-8}{31}\times 100\%$

$\text{Percent decrease}=\frac{23}{31}\times 100\%$

$\text{Percent decrease}=0.741935483\times 100\%$

$\text{Percent decrease}=74.1935483\%$

$\text{Percent decrease}\approx 74\%$

Therefore, there is an approximate 74% decrease in cost per minute for the long distance call from 1978 to 2008.
