A jewelry designer sells bead necklaces in a local farmer's market. The profit P that she makes from selling x necklaces is give n by P = −x2 + 35x. What is the least number of her necklaces she must sell to make a profit of $300.00?
1 answer:
Answer:
15
Step-by-step explanation:
Given that the profit equation from selling x necklaces is
P = −x2 + 35x.
To make a profit of $300, the profit P = 300 then
300 = -x2 + 35x
x2 - 35x + 300 = 0
solve by factorization
x2 - 15x - 20x + 300 = 0
x(x - 15) - 20(x - 15) = 0
(x - 15)(x - 20) = 0
x - 15 = 0 or x - 20 = 0
x = 15 or 20
Since 20 is higher, the least number of her necklaces she must sell to make a profit of $300.00 is 15

It would take Adrian 4 days, if you add 3/4 four times all together you will end up with 12/4. Then you have to simplify it, getting the answer 3. Hope this helped! :)
