Question

The cost for Andrea to produce several units of a certain item is $336 plus $12 per unit. She sells this item for $28 per unit.



How many units of the item must she produce and sell so that the amount of money she earns in sales equals the amount of money she spends in production costs? How much money would that be?



She would have to produce and sell units of the item. Her costs and her earnings would both equal $ .

Answer 1

have you written an equation for the cost of production.

you will also need an equation for the sales...

Answer 2

about 12 units

Answer 3

let u be the units produced

C(u) = 12u + 336 COST

S(u) = 28u Sales

Now cost = sales in break even so

S(u) = C(u)

or

28u = 12u + 336

now solve for u.

the answer will need to be an integer
