Question

The sale price of every item in a store is 85% of its usual price. Find the price of the following items given their usual price. The usual price of a soccer ball is $19.80, what

is its sale price?

Answer 1

$16.83

Explanation:

If the usual price is $19.80 and they are on sale for 85% of the usual price, you can set this up in the form of a proportion.

`(85)/(100) = (x)/(19.80)`

With this, you first multiply 85*19.80 and then you divide that answer by 100 to solve for x, the sale price.

Another way you can approach it is by changing 85% into it's decimal form (.85) and multiplying this by the original price (19.80).
