x

So ;

Mr.Lopez \:   \: had \:  \:  \frac{92.5}{100}x \\

_________________________________

Mrs.Foster \:  \: had \:  \:  \frac{19}{20} x \\

So :

Mrs.Foster \:  \: had \:  \:  \frac{19 \times 5}{20 \times 5} x \\

Mrs.Foster \:  \: had \:  \:  \frac{95}{100}x \\

Ms.Kelly \:  \: had \:  \: 0.9x

Ms.Kelly \:  \: had \:  \:  \frac{9}{10} x \\

Ms.Kelly \:  \: had \:  \:  \frac{90}{100} x \\
