Lets say you are x
20<2x<40
therefore x has to be greater than 10, but less than 20
6x=_8
the only numbers between 10 and 20 that works with this equation are 13 and 18
(6x13=78 and 6x18=108)
Ruth’s new floor cost $432.
The cost can be calculated as follows.
First, calculate the area of dining room. Use the formula of rectangle area (width x length)
Area = width x length
= 6 yd x 9 yd
= 54 sq yd
Second, calculate the total cost.
Cost = 54 sq yd x $ 8 per sq yd
= $ 432
Hence it cost $ 432 to install the new wood floor.
