Answer:
115 are not minivans.
Step-by-step 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:
[tex]\frac{2 \text{ mini}}{7\text{ total}}=\frac{x}{161\text{ total}}[/tex]
We need to solve for x. Cross multiply:
[tex]322=7x[/tex]
Divide both sides by 7:
[tex]x=46[/tex]
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!
