Company A manufactures and sells gidgets. The owners have determined that the company has the monthly revenue and cost functions

jasenka [17]

Answer:

Option A. 356 gidgets

Step-by-step explanation:

we have

R(x) ----> the monthly revenue function

C(x) ---> the monthly cost function

x ----> the number of gidgets sold

$R(x)=16x$

$C(x)=12x+1,424$

we know that

Break-even means that the revenue equals cost

$16x=12x+1,424$

solve for x

$16x-12x=1,424$

$4x=1,424$

$x=356\ gidgets$
