First, determine the amount of ground turkey that is used for the first 6 burgers by multiplying the number of burgers with the amount used.
n = (3/8 lb)(6 burgers) = 2.25 pounds
Subtract this from the total amount of ground turkey by subtracting the answer from 3.
W = 3 - 2.25 lbs
W = 0.75 lbs
Divide W by 1/4 to determine the final answer,
m = 0.75 lbs/ 1/4 = 3
ANSWER: 3
