Question

if 300 jelly beans cost you x dollarshow many jellybeans can you purchase for 50 cents at the same rate

Answer 1

You can get 300 jellybeans for x dollars.
So you would get n jellybeans for 0.50 dollars.

Doing this as similar ratios:
300 ... n
----- = ---
..x .....0.50

Cross multiplying you get:
150 = nx

n = 150/x

It depends on x, but you can by 150/x jellybeans for 0.50.

For example if you could buy 300 jellybeans for 5 dollars, you could buy (150/5) = 30 jellybeans for 0.50.

Answer 2

Let y= the number of jelly beans at 1/2 dollar
300/x= y/(1/2)
y= 150 /x
So if you buy 300 jelly beans for 3$, then you can buy
150/3= 50 jellybeans for 50 cents = 1/2 dollar

Answer 3

per jellybeans cost = x/300 per jellybean

# of jelly beans for 50 cents = 0.5 dollar(300)/X = 150/X

Answer 4

300 jellybeans for x dollars
so, you can get 300/x jellybeans for one dollar.
Since you have 50 cents (half dollar), you divide that quantity by two.
(300/x) * (1/2) = (150/x) jellybeans!

Answer 5

50

Answer 6

what does x=?
if x= 1 dollars then you can buy 150 jelly beans for 50 cents

Answer 7

you get 300 jellybeans divided by x times 100(to get it in cents)
and you multiply the results by 50.
you need to do your own homework.

Answer 8
