To answer this question we will use the following expression to compute the percentage that x represents of y:
[tex]\frac{x}{y}*100\%.[/tex]
The total amount spent on education is:
[tex]\text{\$}136+\text{\$}170+\text{\$}90=\text{\$}396.[/tex]
The total amount is:
[tex]\text{\$}400+\text{\$400+\$70+\$136+\$70+\$90+\$170+\$170+\$294=\$1800. }[/tex]
Therefore the percent of total take-home pay used for education is:
[tex]\frac{\text{ \$}396}{\text{ \$}1800}*100\%=22\%.[/tex]
Answer: 22%.
