Marie is redecorating her bedroom and decides to paint 3 of the walls. Each of the walls measure 12 feet by 10 feet. How many square feet will she need to paint?

360 ft²

Step-by-step explanation:

there are 3 walls

one full wall has area:

12*10=120 ft²

total = 120*3 = 360 ft²

$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
