1. A jewelry maker incurs costs for a necklace according to

C(x) = 35x + 1650

If the revenue function for the necklaces is

R(x) = 85x

how many necklaces must be sold to break even?

2. A manufacturer of shower-surrounds has a revenue function of

R(x) = 81.50x

and a cost function of

C(x) = 63x + 1850

Find the number of units that must be sold to break even?

C(x) = 35x + 1650

If the revenue function for the necklaces is

R(x) = 85x

how many necklaces must be sold to break even?

2. A manufacturer of shower-surrounds has a revenue function of

R(x) = 81.50x

and a cost function of

C(x) = 63x + 1850

Find the number of units that must be sold to break even?
