Question

A farm grew 19.8 tons of wheat in 2013. The farm wheat output increased by 9.8% from 2013 to 2014 and by 5.1% from 2014 to2015. Which expression represents a strategy for estimating the total output of wheat in ton in 2015.

Answer 1

Answer:

Step-by-step explanation:

let x is Wheat grew in 2013

Then x=19.8 tons

in 2014 the growth is 9.8% more

O/p in 2014 =x+9.8x/100=x(1+9.8/100)=109.8x/100

in 2015 the growth is 5.1% more

O/p in 2015=(109.8x/100)(1+5.1/100)

=109.8x/100*105.1x/100=109.8*105.1*x²/100²

=(109.8*105.1/100²)(19.8)²=1098*1051*(198)² / (100)²
