c.) $3.38 Original price = $2.60 * It is the basis of increase thus, 100% * The increase is 30%, thus, 100% + 30% = 130% To get the new price, simply multiply the original price to 130% $2.60 * 130% = $3.38 Another way of solving the problem is getting the equivalent of 30% and adding it to the original price. $2.60 * 30% = $0.78 $2.60 + $0.78 = $3.38
