Answer:
Cell A = 15
Step-by-step explanation:
If 6 spring rolls will serve 3 people, let x be the number of people 30 spring rolls will serve.
Thus,
6 spring rolls = 3 people
30 spring rolls = x
Cross multiply
6*x = 3*30
6x = 90
Divide both sides by 6
6x/6 = 90/6
x = 15
30 spring rolls will serve 15 people.

2) 480
3) 144
4) 2m > 84 $
4m > 168 $
10m> 420 $
13m> 546$
Step-by-step explanation:
1) 582 in 30 mins ... so in third the time 582÷3 = 194
2)120 tools in 5 hours , so 120 ÷ 5 = 24 tools per hour > so 24 × 20 = 480
3) 1kg is for 18$ ... so 8kg will be 8 × 18 = 144
4) 5meters cost 210$ , one meter costs 210÷5 =42
now multiply , 2×42 = 84 , 4×42 = 168 , 10×42= 420 , 13×42 = 546
