Answer :
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.
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.
