Answer:
He is making 20 naira profit for every 4 cups that he sells for 100 naira
Therefore, if he selled all this cups for 100 naira per 4 cups he made a total profit of 100 naira
In this quadratic equation a=9 b=0 c=64, you could use the Quadratic Formula:
x = [-b +-sqrt (b^2 -4*a*c)] / 2*a
x = 0 +- sqrt (0 -4*9*64) / 2*9
x = +- sqrt(-2,304) / 18
x = + 48 i / 18
x = -48 i /18
Where "i" is the square root of minus 1.
