Answer:
[tex]1\:\mathrm{pound}[/tex]
Step-by-step explanation:
We can write the following equation using the information given:
[tex]3x+1x=4[/tex], where [tex]x[/tex] is some constant.
Solving, we get:
[tex]4x=4,\\x=1[/tex].
Therefore, we plug in [tex]x=1[/tex] to find the amount of meat he uses for each type:
Beef: [tex]3x=3(1)=3\:\mathrm{pounds}[/tex]
Pork: [tex]1x=1(1)=\fbox{$1\:\mathrm{pound}$}[/tex].
