Question

The value of U.S exports to China increased from $1480 million in 2011 to $2768 million

Answer 1

The percentage of increase was 87.027... %

Explanation

The value of U.S exports to China increased from $1480 million to $2768 million.

Suppose, the percentage of increase is  $x\%$

So, the amount of increase = $x\%$ of 1480 $=1480*\frac{x}{100}=14.8x$

Thus, the equation will be......

$14.8x= 2768-1480\\ \\ 14.8x=1288\\ \\ x= \frac{1288}{14.8}=87.027....$

So, the percentage of increase was 87.027... %
