Let
x------> the sale price of a jacket
y-----> the original price of a jacket
we know that
[tex] \frac{x}{y} = \frac{3}{4} [/tex] -------> equation [tex] 1 [/tex]
[tex] y=64 [/tex] -------> equation [tex] 2 [/tex]
Substitute equation [tex] 2 [/tex] in equation [tex] 1 [/tex]
[tex] \frac{x}{64} = \frac{3}{4}\\ \\ 4*x= 64*3\\ \\ x=\frac{64*3}{4} [/tex]
[tex] x=48\ dollars [/tex]
therefore
the answer is
the sale price of a jacket is [tex] 48\ dollars [/tex]
