Divide the length in the blueprint by the length in the actual
so
8 in/168 ft
step 2
Multiply the actual wide by the scale to obtain the width in the blueprint
[tex]96\cdot\frac{8}{168}=\frac{768}{168}=\frac{672}{168}+\frac{96}{168}=4+\frac{12}{21}=4+\frac{4}{7}=4\frac{4}{7}in[/tex]answer is option A
