  • 75 % discount on $34.99 =34.99*0.25=8.74
  • Multiply it by three, and divide it by four. This is the amount off. Subtract this from the original price. Or, you can just mutiply by 0.75, which is the same thing, as long as you subtract it.
  • 1) "It requires doing some math in your head. If the price says "$Y," and the discount tag says "X % off," the discounted price is $Y (1-X/100). In English, that means you multiply the percent off by the price, divide by 100, and subtract this from the original price. For example, if the price tag says $24.95, and the sign says "10% off," 10 times 24.95 is 249.5. Divided by 100, that's 2.50 (rounded off), which you subtract from the original 24.95 to give approximately $22.50 (ok, $22.45, but the whole calculation is easier if you realize that $24.95 is very close to $25)."

After simplification, you get as discounted price: $Y (25/100) You just pay 1/4 of the original price.
