What single decimal multiplier would you use to decrease by 6% followed by a 9% decrease?

Explanation:

A 6% decrease means the multiplier is 1-0.06 = 0.94

A 9% decrease means the multiplier is 1-0.09 = 0.91

Multiply those results: 0.94*0.91 = 0.8554

Extra Info:

The final price is 85.54% of the original price after the two discounts are applied (in any order). This represents a total discount of 100% - 85.54% = 14.46%

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
