Ann buys a dress in a sale. the normal price of the dress is reduced by 20%. the normal price is £36.80. work out the sale price! also explain how you calculated it

Hello!

Let's do this step by step!

#1

"Reducing" means to make something smaller, like a discount. So we are reducing the price of the dress by 20%. This means we must first find what 20% of the dress's price is and then subtract that from the price.

#2

36.80 * 20% = 7.36

So, 20% of 36.80 is 7.36. Subtract that: 

#3

36.80 - 7.36 = 29.44

 

The sale price of the dress is $29.44.

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
