Question

Jennifer spent $150 at a craft fair to rent a booth. she sells knit blankets for $25 each. how would you 1.) wright the equation(slope) 2.) how many blankets does Jennifer need to sell to break even

Answer 1

25(x)=150 and 6 blankets 

Answer 2

Answer: Jeniffer wins $25 per blanket. and she must pay $150 to renth the booth.

a) So the equation of Jennifer's profit is P(x) = $25*x - $150.

where x is the number of blankets that she sells, 25*x is positive because that is the money she wins, and the 150 is negative because is the money that she has to pay for the rent.

b) For breaking even, the profit must be equal to zero, it means that she doesn't lose or win anything. Then we do P(x) = 0 = $25*x - $150.

then 25*x = 150

       x = 150/25 = 6

So she must sell 6 blankets to break even.
