There are 16 cups in a gallon. Convert gallons into cups:
![9 * 16 = 144](https://img.qammunity.org/2019/formulas/mathematics/middle-school/hwur2n98bysxyy76a7ywnpml59ukc9bxrg.png)
34 guests ate 2 and 1/2 cups of ice cream. To find the total amount of ice cream they ate, multiply the cups eaten by each guest by the amount of guests.
![34 * 2 (1)/(2) = 85](https://img.qammunity.org/2019/formulas/mathematics/middle-school/woutvym68tefoaflyo3orym8anp0vi043m.png)
Subtract the total amount the guests ate by the amount of cups provided.
![144 - 85 = 59](https://img.qammunity.org/2019/formulas/mathematics/middle-school/8khaksqeypxyzh5yypljtbgic98kjdij1d.png)
There are 2 cups in a pint. To convert cups into pints, divide the cups by 2.
![59 / 2 = 29 (1)/(2)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/yqafi0xz0njqedx3q4p92a8vyhq2gb0q4o.png)
There are
