So lets take a look at what we know:
5% of the tickets were discount
100% of the tickets is equal to 60 tickets
From this information we can create the proportion:
![(x)/(5) = (60)/(100)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/brfzz0rmptk8k2hyy3w1n25i3erzxsf6yx.png)
.
Cross Multiply to get
![100x=300](https://img.qammunity.org/2019/formulas/mathematics/middle-school/aoz1b69f3w8v9x61mh9j2mm3c725ko9lz9.png)
Divide 100 on each side to get
![x=3](https://img.qammunity.org/2019/formulas/mathematics/college/7ps1tadqt6n0r4c5twvavc795rj7e7v09l.png)
.
Three discount tickets were sold.
