What number increased by 40 percent equals 80?
Here's another way to ask the question: If you have a number and increase it by 40 percent you get 80. What is the number? Let x be the number you're looking for. Forty percent of the number can be expressed as 0.40x (because 40% = 0.40). The question said that x is increased by 40 percent, which implies addition, so the equation is x + 0.40x = 80 1.4x = 80 x = 80/1.4 = 57.14
