In a '20% off' sale, a coat was £220. work out the original price.

The original price of the coat was £ 275

Step-by-step explanation:

1. Let's review all the information given for solving this question:

Sale price of the coat = £ 220

Discount from the original price = 20%

2. Let's find the original price of the coat

Original price of the coat = x

Sale price of the coat = £ 220

Sale price of the coat = x - 20%x

220 = x - 0.2x

220 = x - 2x/10 (0.2 = 2/10)

2,200 = 10x -2x (Multiplying by 10 at both sides)

2,200 = 8x

2.200/8 = 8x/8 (Dividing by 8 at both sides)

275 = x

The original price of the coat was £ 275

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
