You must calculate the number of sheets of plywood needed for subflooring. each sheet of plywood measures 4'by 8. the measurements of the house are 28 by 30' and there is a 12 by 4' hole for the stairs to come up from the basement. how many sheets of plywood will be needed? round up to the nearest sheet

25 sheets of plywood will be needed

Step-by-step explanation:

Each sheet of plywood measures .

We have to cover the surface of the house, minus the surface of the hole of the stairs.

To know how many sheets will be needed, we divide the surface to be covered by the surface of each sheet

As we can't buy 0,75 of a sheet, we round it up, i.e. we will need 25 sheets of plywood for subflooring.

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
