Hello Samson,
203 lbs represents a 40% increase from the previous year.
Suppose x is last year's production. If this year's production is 40% more, it means it equals x + 0.40*x = 1.4x
Now you set 1.4x = 203
Divide both sides by 1.4 ---> x = 203/1.4 = 145 lbs
Check: Start with 145, add 40% of 145 which is 145 * 40% = 58 ----> 145 + 58 = 203
Answer: 145 pounds were harvested last year.
