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

so

16x=12x+1,424

solve for x

16x-12x=1,424

4x=1,424

x=356\ gidgets
