    Example 1: Revenue is 2000, Price is 20, and Tickets sold is 100 not 1000

    Thank you teacher from the Russian mom. I am trying to help my 11 grade son with the similar word problem. I used to be good in this. But 30 years ago. And It was in Russian language. So I have to shake my memory and translate everything in English. Oh boy! Looks like I am still ok. Me and my son solved the problem in two ways. Both times the X vertex is negative. In our case X is amount of weeks, and Y vertex is profit. How come the amount of weeks can be negative?

    It’s less work to find the axis of symmetry in the middle of the two x intercepts… converting to standard form and then using the equation is not as meaning full, it’s more work and it removes the need for understanding the relationships between quadratic features…😢

  • @louiecanadilla3672
    @louiecanadilla36722 жыл бұрын

    #sold is not equal to 1000, it should only be 100, because 50+5(10) = 100 not 1000, therefore the max. revenue should only be 2000.
