Answer:
The value of weighted mean is $24470
Step-by-step explanation:
Weighted mean [tex]\bar{x}[/tex] is given by
[tex]\bar{x} =\frac{w_1x_1+w_2x_2+w_3x_3+w_4x_4}{w_1+w_2+w_3+w_4}[/tex]
In the given question
[tex]w_1=2 ,x_1= \$25090[/tex]
[tex]w_2=3 ,x_2= \$20000[/tex]
[tex]w_3=1 ,x_3= \$21475[/tex]
[tex]w_4=1 ,x_4= \$39638[/tex]
Therefore
[tex]\bar{x} =\$[\frac{2\times25090+3\times20000+1\times21475+1\times39638}{2+3+1+1}][/tex]
=>[tex]\bar{x} =\$24470[/tex]
Thus the value of weighted mean is $24470
