Answer:
7 white and 8 dark bars
Step-by-step explanation:
x white bars
15-x dark bars
cost of white bars is 2 * x
cost of dark bars is 2,5 * (15-x)
Write an equation
2x + 2,5 * (15-x) = 34
2x + 37,5 - 2,5x = 34
-0,5 x = - 3,5
x = 7
So we have x = 7 white bars
and 15 - x = 15 - 7 = 8 dark bars
10 multiplied to 10 is 100.
10 (10) = 100
The equation is y=-2x^2+6
