Define x :
------------------------------------------------------
Let the width be x.
------------------------------------------------------
Find Area of the walkway :
------------------------------------------------------
Area = 30x + 30x + 20x + 20x + 4x²
Area = 100x + 4x²
------------------------------------------------------
Find cost of the walkway in term of x:
------------------------------------------------------
1m² = $10
100x + 4x² = 10(4x² + 100x)
(100x + 4x²)m = $(40x² + 1000x)
------------------------------------------------------
Find Width of the walkway :
------------------------------------------------------
The budget is $6000
40x² + 1000x = 6000
40x² + 1000x - 6000 = 0
x² + 25x -150 = 0 //Divide by 40 through
(x - 5)(x + 30) = 0 //Factorise
x = 5 or x = -30 (Rejected, width cannot be negative)
------------------------------------------------------
Answer: The width can be 5m wide.
------------------------------------------------------
4 spaces because those numbers multiplied is 0.2001
1740 i think.
I added 6000 and 2700 and got 8700. then i divided it by 5 because it going to take 5 years to pay the loan.
Answer: D
Step-by-step explanation: Divide 110 and 1700 to get 15 then multiply that 15 with 110 to get 1600. I hope this helps ;)
