If 300 jellybeans cost you x dollars. How many jellybeans can you purchase for 50 cents at the same rate?

Answer 1

#150/x #

If 300 jellybeans cost x dollars, for each dollar you get #300/x# jellybeans. Since each dollar has two 50 cents, you get #300/(2x)# ie #150/x # jellybeans.

If 300 jellybeans cost x dollars, then the cost per jellybean is x/300 dollars. To find out how many jellybeans you can purchase for 50 cents, you need to divide 50 cents by the cost per jellybean (x/300 dollars) and multiply by 100 to convert cents to dollars. So, the number of jellybeans you can purchase for 50 cents would be (50 / (x/300)) * 100.
