We are given a circle graph that shows the time spent on homework last week.
Jacob spent a total of 16 hours doing homework.
The time spent on doing science homework is given by
[tex]\begin{gathered} t_{\text{science}}=25\%\: of\: 16 \\ t_{\text{science}}=\frac{25}{100}\: \times\: 16=4\: \text{hours} \end{gathered}[/tex]The time spent on doing band practice is given by
[tex]\begin{gathered} t_{\text{band}}=12.5\%\: of\: 16 \\ t_{\text{science}}=\frac{12.5}{100}\: \times\: 16=2\: \text{hours} \end{gathered}[/tex]The difference between the time spent on science homework and band practice is
[tex]difference=t_{\text{science}}-t_{\text{band}}=4-2=2\: \text{hours}[/tex]Therefore, Jacob spent 2 more hours on science homework than band practice.
