Answer 1

$ 5 is taken is off the regular price

Solution:

Given that, Regular price of the soccer ball is $ 25

During the sale, it is 20 percent off

Let "x" be the amount that is taken off the regular price

Regular price = $ 25

Discount = 20 percent off

Which means, 20 % of regular price is taken off

x = 20 % of regular price

x = 20 % of 25

$x = \frac{20}{100} \times 25\\\\x = 5$

Thus $ 5 is taken is off the regular price
