Answer 2

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*(x)/(100)=14.8x`

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

`14.8x= 2768-1480\\ \\ 14.8x=1288\\ \\ x= (1288)/(14.8)=87.027....`

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