Question

The ratio of the sale price of a jacket to the original price is 3:4 the original price is $64 what is the sale price

Answer 1

the ratio 3:4 can be written as 3/4

you will then be looking for three quarters of the origional price to get the sale price.

so: 3/4×64=192/4
=$48

Answer 2

Let

x------> the sale price of a jacket

y-----> the original price of a jacket

we know that

`(x)/(y) = (3)/(4)` -------> equation
`1`

`y=64` -------> equation
`2`

Substitute equation
`2` in equation
`1`

`(x)/(64) = (3)/(4)\\ \\ 4*x= 64*3\\ \\ x=(64*3)/(4)`

`x=48\ dollars`

therefore

the answer is

the sale price of a jacket is
`48\ dollars`
