Question

A set of golf clubs is on sale for $150.00, which is 70% off of its original price. What was the original price of the golf clubs?

Answer 1

$500

Explanation:

Let x be the original price, then:-

x - 0.70x = 150

x = 150 / 0.30

= $500

Answer 2

So, let's start with the sale. 70% off. So, we know that 150 is 30% of the total price (since 70% is being taken off)

In order to solve this, we need to set up an equation.

Let x = the starting price before sale.

`x*.3=150\\\\x=150/.3\\x=500`

The price before sale of the golf clubs is $500

When you multiply something by a decimal, thats the percentage you have of it. So, when you multiply any number by .3, that is 30% of the original price. Since we decided that 70% off is the same as 30% of the original price, we can use the equation above to find 30 percent of the price, instead of having to subtract 70% of 500 from 500.
