We let x be the number of cameras that need to be sold. The total cost for manufacturing x cameras is,
9x + 1800
a. To equal its daily cost, the equation would be
9x + 1800 = 18x
The value of x from the equation is 200.
b. For 250 cameras sold,
18(250) - ((9)(250) + 1800) = 450
Therefore, the answer is letter B.
Answer:
Length 7metres
Perimeter 28 metres
Step-by-step explanation:
Area of a square is L²
To get the length of one side is thus√L²
√49=7 metres
Perimeter will be length by 4
7×4=28 metres
C is the answer for your question
-8x+18y=-12
24x-18y=18
16x=6
X=3/8
Y=3-12)/6
y=-3/2
