Question

Ronaldo purchased a new golf club that originally sold for $65.00. He bought it at a 15% discount. What was the sale price?

Answer 1

`$55.25`

Explanation:

There are three methods.
Method 1
Find 15% of 65. This is the amount of discount.
Subtract the discount from $65.

`15/100 xx65 = $9.75`

`$65- $9.75 =$55.75`

Method 2
If there is a discount of 15%, it means that only 85% is being paid.
Find `85% of 65`

`85/100xx 65 = $55.25`

Method 3

Use direct proportion to compare 100% to 85%

`100/65 = 85/x`

`x = (65xx85)/100`

`x = $55.25`
