Answer 1

20 noisemakers; 40 balloons; 5 napkins

Explanation:

n = noisemakers amount

b = balloons amount

k = napkins amount

n/4 = k

b = 2n

b + n + k= 65

plug first and second equation into the respected variables in the 3rd equation so:

2n + n + n/4 = 65

multiple both sides by 4 to get rid of fraction

4(2n + n + n/4) = 4*65

8n + 4n + n = 260

13n = 260

n = 20

use n = 13 to get the other variables

b = 2(20)

b = 40

(20)/4 = k

k = 5
