A fashion store is having a sale advertising 'one third' off all prices. If a pair of trousers costs £54.24 in the sale, what did it cost before?

162.72

Step-by-step explanation:

Let's take the final price as x

What has been said is that before the sale, the price had been 3x, since the price would be three time higher. After the sale we divide the price by 3 and get price in the question. So, 53.24 multiplied by three is equal to the initial price before the sale. 1/3, just means that everything is cut off 3 times. You can prove this be adding 54.24, the price now, with two times itself or just multiplying 54.24 by three.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
