Answer:
Part A: See detail below.
Part B: Company B charges less than company A for 8 windows.
Part C: The saving using company B for 6 windows is $3.
Step-by-step explanation:
Part A:
Company A: (total charges) = ($6)x(N number of windows)+($12)
Company B: (total charges) = ($5)x(N number of windows)+($15)
Part B:
Company A for 8 windows: 6*8+12=$60
Company B for 8 windows: 5*8+15=$55
Part C:
(Saving) = (6*6+12)-(6*5+15)=48-45= $3
We know that the sandbox is square, and that the area is 160 sq ft. Since A = s^2 for a square, let's work backwards and find s if A = 160 sq ft = s^2.
s^2 = 160 = 16(10). We do this because 16 is the largest perfect square factor of 160.
Then the length of one side of the square is approx. s = 4√10 ft (12.65 ft)
12 - 15 ÷ 3 + 9
Following BODMAS = Bracket Order Division Multiplication Addition Subtraction
Division comes before Addition and Subtraction, so we carry out Division first.
12 - 15 ÷ 3 + 9, 15 ÷ 3 = 5
12 - 5 + 9
7 + 9
16
