Hi there!

It depends on the dimensions of each cords of wood.  If each cord of wood is just one square yard large, then you could fit 4*4*2=32 cords of wood into a room that has the dimensions that you described.

A salesman priced a four wheeler at $3,500 the first day it was on the market. The second day he reduced the price by 10%. What
Karo-lina-s [1.5K]

Answer:


$3,150

Step-by-step explanation:

To find the sale price, multiply the original price ($3,500) by 0.90.  This 0.90 comes from subtracting 10% from 100% and converting the result to the decimal fraction 0.90.

0.90($3,500) = $3,150
