Question

1) Lorraine would like to purchase a new pair of boots that cost $80. She has a coupon for 25% off.

Answer 1

Answer:

A) X represents the new price of the jacket after adding the coupon

B) There's a 100 in the denominator of the first ratio because it was originally a percentage, you multiply the percentage by 100 to figure out the decimal.

C) Cross multiply:

100x-2000

Then subtract 100 by both sides:

(100 cancels out each other) 100x-2000

    2000-100= 1900                                                  

X=1900      

Answer 2

Answer:

$60

Step-by-step explanation:

25/100x80=20

80-20=60
