Answers: 3
![Pennies=\frac{11}{20}\ of\ total\ coins\\\\Nickels=\frac{4}{20}\ of\ total\ coins\\\\Nickels+Pennies=(\frac{11}{20}+\frac{4}{20})\ of\ total\ coins=\frac{3}{4}\ of\ total\ coins\\\\Quarters=[1-(Nickels+Pennies)]\ of\ total\ coins=[1-\frac{3}{4}]\ of\ total\ coins=\frac{1}{4}\ of\ total\ coins\\\\Quarters=\frac{1}{4}\times 240=60](/tpl/images/0460/4481/6827d.png)
