18.75%
Assuming you're asking for percent increase heres how the problem is solved
1 - Understanding the formula for percent increase
[tex]Percent~Increase= \%[/tex]∧[tex]= |\frac{New~amount~-~Original~amount}{Original~Amount}|[/tex] x 100
2 - Plug it in
%∧ [tex]= |\frac{9.50~-~8.00}{8.00}| * 100 = |\frac{1.50}{8.00}| * 100 = | 0.1875 | * 100 = 0.1875 * 100 = 18.75\%[/tex]
Hope this helps :)
