William bought a new sweater at the store when they were having a 45%, off sale. if the regular price of the sweater was $19, how much did william pay with the discount?

Firstly, to calculate a price you need to change the percentage into a decimal. You do this by dividing it by 100.

45 / 100 = 0.45,
The discount price will be 55% of the original price,
55 / 100 = 0.55,
19 * 0.55 = 10.45,

So the discound price will be $10.45

Hope this helps!
