Answer:
you gatta show the picture
Step-by-step explanation:
If you have 8 yellow balloons for every 12 blue balloons, then if you have 20 balloons in total, 8 out of 20 of those balloons will be yellow. Then you can set up this ratio:
![\frac{8yellow}{20total} = \frac{Xyellow}{100total}](https://tex.z-dn.net/?f=%5Cfrac%7B8yellow%7D%7B20total%7D%20%3D%20%5Cfrac%7BXyellow%7D%7B100total%7D)
Then, you can use either cross multiplication or multiply the numerator and denominator by the same number to help solve for x. Personally, I prefer cross multiplication, so that's what I'll show you here:
![\frac{8yellow}{20total} = \frac{Xyellow}{100total} \\ 8yellow*100total=20total*Xyellow](https://tex.z-dn.net/?f=%5Cfrac%7B8yellow%7D%7B20total%7D%20%3D%20%5Cfrac%7BXyellow%7D%7B100total%7D%20%5C%5C%208yellow%2A100total%3D20total%2AXyellow)
Finally, solve for x:
![8yellow*100total=20total*Xyellow \\ 8*100=20*x \\ 800=20x \\ 800/20=20x/20 \\ x=40yellow](https://tex.z-dn.net/?f=8yellow%2A100total%3D20total%2AXyellow%20%5C%5C%208%2A100%3D20%2Ax%20%5C%5C%20800%3D20x%20%5C%5C%20800%2F20%3D20x%2F20%20%5C%5C%20x%3D40yellow)
If you had 100 balloons, you will have
40 yellow balloons.
Hope this helps!!
Answer:
11.33
Step-by-step explanation:
First find the markup
