Answer :
The weight gained by Cricket within the 1-year period would be 8.75 or 8 3/4 pounds.
- Cricket weighed 3 3/4 pounds initially and 12.5 pounds after one year.
- In order to calculate the weight gained within the said period, the initial weight would be subtracted from the final weight.
Thus:
Weight gained = 12.5 - 3 3/4
= 12.5 - 3.75 or 12 1/2 - 3 3/4
= 8.75 or 8 3/4
