Question

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

A. 150/x
B. 150x
C. 6x
D. x/6
E. 1500x

Answer 1

So first, lets set up a proportion:\[\frac{300}{x} = \frac{n}{0.5}\] where n is your answer. Multiplying both sides by 0.5, the answer is 150/x, or A.
