let x represent the initial amount of money
x + .08x = 237.60
1.08x = 237.60
x = $220.00

The friend had the original 100% plus an 8% increase, so in total he/she received 108%.
So, the $237.60 equals 108%. Divide 237.60 by 108 then multiply by 100 to find out what the original 100% was:
($237.60 / 108) * 100 = $220.00
More correctly you would divide by 1.08 then multiply by 1.00 - obviously you don't actually need to multiply by 1 though!!

before the increase she made $220.00. to solve this you do NOT multiply by .92, you take the after pay (237.60) and divide by 1.08 to get the correct result.

Divide the pay by 1.08.
