The total mass of all the beans in the Jar-O-Beans is 7.30kg. Knowing the average bean mass and the % abundance of each type of bean, calculate the total number of beans in the jar and the number of each type of bean.

Also the answer should be in grams.

Thank you for the opportunity to help you with your question!

total mass = 7.30kg

take the average bean mass to be Xg

1kg=1000g

thus the total number of beans= 7300g/Xg

the number of each type of bean is:

(% abudance/100)*(7300g/Xg)
