Answer:
300 bags of wheat
Step-by-step explanation:
We can get the answer by using algebraic expressions. If 1,200 bags means a 20% decrease in the yield from 2005, then it is 80% of the yield in 2005.
Let's solve.
Let x be the number of bags yield from 2005.
We can say: 1,200 is 80% of x
1,200 = 80% of x
1,200 = 0.80(x)
x = [tex]\frac{1,200}{0.80}[/tex]
x = 1,500
The number of bags yield from 2005 is 1,500.
Let's check.
Let x be the decrease in yield.
1,500 x 20% = x
1,500(0.20) = x
x = 300
The 20% decrease in yield is equal to 300 bags of wheat.
1,500 - 300 = 1,200 bags
The answer is correct.
