Suppose you have $20 to spend on party decorations. Balloons are $0.05 each, streamers are $0.25 each, and noisemakers are $0.40
sergejj [24]

[C] 0.05b + 0.25s + 0.4n = 20

b = balloons

s = streamers

n = noisemaker

Since they already give us the price of each item we just need to add a variable at the end of each one since we don't know how many of each item is bought. Adding the costs of all the party supplies should not go over $20. We can automatically eliminate B and D. We can also eliminate A because the prices of each item are incorrect. Therefore, C is the correct answer.

Best of Luck!
