1A coat is on sale. The original price of the coat is $82. The sale price is $74.50. A. What is the discount amount?

B. What is the discount expressed as a percent change?

somebody please help me.

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%

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
