QUESTION:Matt buys a TV for \pounds 550, and a year later sells it to his friend Dave for 32\% less. Calculate how much Dave purchased the TV for.

 

ANSWER: This is a 32\% decrease, so the multiplier for a 32\% decrease is

1-\dfrac{32}{100}=0.68

Next we need to multiply the original amount by 0.68 to get our final answer. 

550\times 0.68=\pounds 374
