Let the original price of the computer be $100.
During the sale, the price was reduced by 20%, so the sale price was 0.80 * $100 = $80.
To restore the price back to the original $100, the price needs to be increased by $100 - $80 = $20.
To find the percent increase, we calculate: (Increase in price / Original price) * 100% = ($20 / $80) * 100% = 25%.
Therefore, the price needed to be increased by 25% to restore it to the original price.
During a sale the price of a computer was reduced by 20%. After the sale the price was increased back to the original price. By what percent was the price increased to restore it to the original price
