Sid and Libby are planning to sell pies
at a local fair. They spend $200 to rent
a table at the fair. Their costs for
ingredients, other supplies, baking, and
packaging are $3.00 per pie. Sid and
Libby plan to sell the pies for $8 each.
How many pies must they sell at the fair
before they start making a profit?

  1. whene revenue > cost, then there's a profit. So, for p pies, we need

    8p > 200 + 3p

  4. Ok child's
    200+3(n)=8(40)
    320=320
    200+3(41)=8(41)
    323=328
    The answer is 40 and sorry for not explaining but I'm in a hurry I used the substitution method :)
