Due to recent bad weather, the price of lemons went up by 220% at the local market.
1. If the old price was 35 cents per lemon, what is the price after the increase?
2. What percent of the new price is 35 cents?

.35 x 2.20 = .77
.77 + .35 = $1.12
The new price is $1.12
.35 is 31% of $1.12

1. To increase one number by a percentage, change the percent to a decimal figure (220% = 2.20) and multiple the first number by the percent. (Note: If the percent was less than 100%, you would then need to add the result to the original amount, but that does not apply here.)
.35 x 2.20 = .77 or 77 cents (Sanity check: 77 cents is more than two times 35 cents, and a 220% increase should inflate the price to more than twice the original amount)
2. .35 = (x%).77
divide both sides by .77 to get the unknown on one side of the equation, thus
.35/.77 = x% or .454545 = 45% (Sanity check: 35 cents is less than half of 77 cents so 45% makes sense.)

1) The price after the increase = .35(1+ 2.20) = .35 x 3.220 =
$ 1.127
2) The percent = (.35 x 100) / 1.127 = %31.056
