Answer:

A. $7.50

B. 9.15%

Step-by-step explanation:

Difference of 82 and 74.50 = |82 - 74.50|/((82 + 74.50)/2) = 7.5/78.25 = 0.095846645367412 = 9.5846645367412%

74.50 is a 9.1463414634146% decrease of 82.

Percentage of decrease = |82 - 74.50|/82 = 7.5/82 = 0.091463414634146 = 9.1463414634146%
