Question

step 12: determine the sizes of the flocks in the third generation
flock x flock y flock z
total pieces of food eaten 32 180 88
food percentage* % 60 % %
simulated number of birds in flock for 3rd generation** 3 18 9

• 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

Divide the total pieces of food eaten by Flock X ($32$) by the total number of pieces of food eaten ($300$).
$Food\ Percentage_{X}=\frac{32}{300}\approx 10.67\%$

Step2: Calculate Food Percentage for Flock Z

Divide the total pieces of food eaten by Flock Z ($88$) by the total number of pieces of food eaten ($300$).
$Food\ Percentage_{Z}=\frac{88}{300}\approx 29.33\%$

Answer:

Flock X Food Percentage: $10.67\%$, Flock Z Food Percentage: $29.33\%$
