c.$20
d.$50
e.$18
f.$6
g.$23
h.$4
i.$42
j.$10
k.$8

Answer 1

2 balloons = h/4 15 balloons = a/30 10 balloons = c/20 21 balloons = i/42 3 balloons = f/6 4 balloons = k/8 5 balloons = j/10

Explanation:

Every time you have a number of balloons, since each costs 2 dollars, you would double the number of balloons to get the price of all of the balloons! Hope this helps! Have a great day!
