To take 30% off a price, you can either find the discount amount and subtract it, or directly calculate the remaining 70% you'll pay; both involve converting 30% to 0.30, then either calculating Original Price x 0.30 (discount) and subtracting, or Original Price x 0.70 (final price) to get the final price instantly.
To calculate a percentage, divide the "part" by the "whole" and then multiply the result by 100; the formula is (Part / Whole) x 100 = Percentage. For example, to find what percentage 15 is of 60, you'd do (15 / 60) = 0.25, and then 0.25 x 100 = 25%. Percent means "per hundred," so it's a way to express a fraction as a number out of 100.
"30% off" means you pay 70% of the original price, so you calculate the discount by multiplying the price by 0.30 (or dividing by 10 and multiplying by 3) to find the amount saved, then subtract that from the original price to get the final cost. For example, 30% off $100 is a $30 saving, making the final price $70.
The number is 300.
For numbers that aren't easily divisible, you can use the 1% method. First, calculate 1% of the number by moving the decimal point two places to the left. Then, multiply this result by the percentage you need. For example, to find 17% of 250: 1% of 250 is 2.5, so 17% would be 17 × 2.5 = 42.5.
