Question

Suppose the store wants to earn a daily profit of $150 from the sale of soccer balls. to earn this profit, what price should the store charge for each soccer ball? explain how to solve this problem.

Answer 1

Sample Response: need to solve the equation 150 = -6x2 + 100x - 180. I can subtract 150 from both sides and use the quadratic formula to find x = 4.53 and 12.13. This means that if the store sells soccer balls for $4.53 or $12.13, it will earn a daily profit of $150.

Answer 2

need to solve the equation 150=-6x2+100x-180.  you can subtract 150 from both sides and use the quadratic formula to find x=4.53 and 12.13. this means that if the store sells soccer balls for 4.53$ or 12.13$ it will earn a daily profit of 150$
