Answer:
115 are not minivans.
Explanation:
So, every for every 2 minivans, there are 5 other types of vehicles.
In other words, out of 7 vehicles, 2 are minivans.
In a fraction, this is 2/7.
To find the number of minivans given 161 total vehicles, we can write a proportion. So:
![\frac{2 \text{ mini}}{7\text{ total}}=\frac{x}{161\text{ total}}](https://img.qammunity.org/2021/formulas/mathematics/high-school/tl2b2yjbtrs1cjeidq9hysngcy5hn08pj5.png)
We need to solve for x. Cross multiply:
![322=7x](https://img.qammunity.org/2021/formulas/mathematics/high-school/23wap23sqlmd7k5q2sp6aahdg2wd6vln06.png)
Divide both sides by 7:
![x=46](https://img.qammunity.org/2021/formulas/mathematics/high-school/794ugnzbyn6opyoz8x1qm0ln2kj85uz20j.png)
So, given 161 total ehicles, 46 of them are minivans.
This means that 161-46 or 115 are not minivans.
So, our answer is 115.
And we're done!
