To find the percent increase, you must find the amount of increase and compare it with the original amount. So the proportion in this case would be x/100 = 30/350, and the answer is about 8.57%
Alternatively, one could use the proportion x/100 = 380/350 (again putting the original on the bottom, because that is what the increase is BASED on). This gives a percent of 108.57% which we interpret as 100% for the original and 8.57% for the increase.

Amount of increase=380-350=30
Therefore percentage of increase=(30/350)X100%
=8.57%

x/100 = 350/380
soooooooo
divide 350/380 then multiply by 100 = " "%

You can make an equation and solve.
350x = 380
x = 380 / 350
x = 1.085714
Since 350 is already the 1 in the 1.08, your increase is .0857 or 8.57%
