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.
[tex]x*.3=150\\\\x=150\div.3\\x=500[/tex]
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.
Answer:
$500
Step-by-step explanation:
Let x be the original price, then:-
x - 0.70x = 150
x = 150 / 0.30
= $500
