Amy bought a sofa on sale for $511. This price was 27% less than the original price. What was the original price?

This price was 27% less than the original price...

this means that the price Scott paid was 73% of the original price.

(0.73) * (original price) = 511

solving for original price:  original price = $ 700

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

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
