Question

a department store is having a building sale where all buildings is 20% off the original price P if the price for a wedding item during the cell can be represented by the expression 0.75 P which expression also represents the price of the item

Answer 1

when taking the discount of 25% off, we first write it as a decimal

25% = 0.25

if we want to take 25% off the 100%, we also write 100% as a decimal

100% = 1

now the difference between the will be

`1-0.25`

this has to be multiplied by the original price

`p\cdot(1-0.25)`

distribute the p into the parentheses

`p-0.25p`

expression c can also be used to express the price of the item
