Three bags of jelly beans contain 26, 28, and 30 beans. The ratios of yellow beans to all beans in each of these bags are 50%, 25%, and 20%, respectively. All three bags of candy are dumped into one bowl. To the nearest percent, what is the percentage of yellow jelly beans in the bowl?

26 +28+30 =84 jelly beans in all 3 bags.

 

[50% x 26 ] + [25% x 28] + [20% x 30] =13 + 7  + 6 =26 - yellow beans in the bowl.

 

26 / 84 =30.95% =~31% of them are yellow.
