Question

flock x flock y flock z
total pieces of food eaten
(from previous page) 123 99 78
food percentage* % % %
simulated number of birds in flock for 2nd
generation**

• divide each flocks total pieces of food by 300, the total

number of pieces of food eaten.
** multiply the food percentage for each flock by the total
number of birds (30).

Explanation:

Step1: Calculate Food Percentage

For Flock X: $\frac{123}{300}\times100 = 41\%$
For Flock Y: $\frac{99}{300}\times100 = 33\%$
For Flock Z: $\frac{78}{300}\times100 = 26\%$

Step2: Calculate Simulated Number of Birds

For Flock X: $0.41\times30 = 12.3\approx12$
For Flock Y: $0.33\times30 = 9.9\approx10$
For Flock Z: $0.26\times30 = 7.8\approx8$

Answer:

Food Percentage: Flock X - $41\%$, Flock Y - $33\%$, Flock Z - $26\%$; Simulated Number of Birds: Flock X - $12$, Flock Y - $10$, Flock Z - $8$
