Question 1

Image of a bicycle

Zoe bought a bike on sale at 15% off the original price.

The original price was $420.

How much did Zoe pay for the bike?

Solution

Method 1

15% = $\dfrac{15}{100}$ = 0.15
Selling price	= Original price − 15% of the original price
	= 420 − 15% × 420 (15% can be entered into a calculator using the % button.)
	= 420 − 0.15 × 420
	= $357.
Zoe paid $357 for the bike.

15% = \(\dfrac{15}{100}\) = 0.15
Selling price	= Original price − 15% of the original price
	= 420 − 15% × 420 (15% can be entered into a calculator using the % button.)
	= 420 − 0.15 × 420
	= $357.
Zoe paid $357 for the bike.
