Point has no dimensions !!
I think you just have to add all of the totals up??
Hi,
Work:

To find the cost of gallons spend for 310 miles you need to first find the amount of gallons consumed on 310 miles path.

If each costs 3.5$ you need to multiply gallons with money.

You would spend 38.745$ to drive 310 miles.
Hope this helps.

Step-by-step explanation:
<h2> l=P×R×T</h2><h3> 6000=2160×X/100×9</h3><h3> 6000÷194.4</h3><h2> =30.86%</h2>
5 girls : 4 boys
5 + 4 = 9 students
= 27 students ( 5girls / 9 students )
*cancel students units*
= 27 ( 5 girls / 9)
= 15 girls
