Step-by-step explanation:
Parts + 3($40 labor)=183.30
parts + 120=183.30
parts=63.30 but it includes tax. To find costs of parts before tax you
63.30/1.055=60 so parts are $60
or to solve with one equation:
parts(1.055) + 3($40 labor) = 183.30
parts(1.055) + 120=183.30
parts(1.055)=63.30
Parts = 63.30/1.055
parts = 60
A = L * W
L = 56 , W = ?, A = 1,792
Now.
1,792 = 56W
W = 1,792 / 56
W = 32
The wide of the door is 32 centimeter.

Hmm, I think you would take 40 and multiply it by 2 because her sister used "twice as many". Then I'm pretty sure you would take your answer from that and divide it by 2 because she used that amount of paper in "half the number of days"?
40 x 2 = 80 all together used
80 / 2 = 40 how many used each day
Is that what you were asking? If I'm wrong let me know please
