Calculations.

Food percentage:

Flock X = 57/300 * 100% = 19%

Flock Y = 153/300 * 100% = 51%

Flock Z = 90/300 * 100% = 30%

Simulated Number of Birds in Flock for 2nd Generation

Flock X = 19% * 30 = 6

Flock Y = 51% * 30 = 15

Flock Z = 30% * 30 = 9

complete the square on the right side of the equation;

-5(x + 0)^2 + 15

answer: d. y = -x^2 + 15
