Question

Judie bought a new necklace. The original price was $80 and the discount was 15% off. What was the sale price of the necklace?

Answer 1

Answer:

$68

Step-by-step explanation:

First, find out what 15% of $80 is. 15% as a decimal is 0.15. Multiply 0.15 and 80 together.

0.15 x 80 = 12.

Now, subtract 12 from the original price, 80.

80 - 12 = 68.

Answer 2

Answer:

I can solve with 2 methods:

I. Because the discount is 15 % of 18 $ , the price will be (100-15=85) 85 % of 18 $

18*85/100= 15,3 $ ( the sale price)

II. The discount is 15 % of 18$

15*18/100= 2,7$  ( the discount)

then I decrease it from the regularly price

18$-2,7$=15,3 $ (the sale price)

Personally I believe the first is an easier method.

I hope you understand and you can apply this in every similary problem.
