Answer:
10 large boxes and 5 small boxes
Step-by-step explanation:
small box = 200n
large box = 500n
2(500n) + 200n = 6000
1000n + 200n = 6000
1200n = 6000
n = 5
5(200) = 1000
6000-1000= 5000
5000 ÷ 500= 10
Since the contractor bought twice as many large boxes as small boxes, we can see 10 is twice as many as 5.
