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

$\frac{x}{y} = \frac{3}{4}$ -------> equation $1$

$y=64$ -------> equation $2$

Substitute equation $2$ in equation $1$

$\frac{x}{64} = \frac{3}{4}\\ \\ 4*x= 64*3\\ \\ x=\frac{64*3}{4}$

$x=48\ dollars$

therefore

the answer is

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