Answer

Explanation:

Step1: Convert fractions to decimals

  • $\frac{1}{2}=0.5$, $\frac{1}{4}=0.25$

Step2: Calculate the weight month - by - month

  • Start with the initial weight (W_0 = 55.75) pounds.
  • After January - March: (W_1=55.75 + 2.125=57.875) pounds.
  • After April - June: (W_2=57.875-0.25 = 57.625) pounds.
  • After July - September: (W_3=57.625 - 0.5=57.125) pounds.
  • After October - December: (W_4=57.125+0.875 = 58) pounds.

Answer:

(58) pounds
