1. .7(255) = $178.50 + .055(178.50) = $188.32
2. 36/ 90 = n/ 100
36 x 100 = 90n
3600= 90n
n= 40
price decrease: 60%
3. 120(1.25) = $150

You're lucky I feel sorry for you (math was a frustrating subject to me until I realized it's like completing a puzzle which makes it more fun).
1. 255.00 X .30 = 76.50
255.00 - 76.50 = 178.50
178.50 x .055 = 9.82
178.50 + 9.82 = $188.32
Final Answer = $188.32
2. 90 - 36 = 54
54 / 90 = 60%
Final Answer 60%
3. 120 x 1.25 = 150.00
120 + 150 = $270
Final Answer = $270

printer $255 .less 30%= 178.50 plus tax at 5.5 =178.50 plus 98.18 =278.68. Too late for me to figure the% decrease in stock.Think it is 48.6 % not sure. last ans is 125% increase= 150.00 +120.oo last year = $270.00 this January. You really should check my math. I am tired. Good Luck and good night.

1. ($255 times .70) times 1.055 = your answer
2. (90-36) DIVIDED BY 90
3 $120 times 2.25 =
ok now they are set up - do it
