HP Printing shipped 30 boxes of printer paper to a retail store. Small boxes contain six packs of paper each, and large boxes contain eight packs. A total of 210 packs of paper were shipped. How many large boxes were sent?

15

Step-by-step explanation:

Let the small boxes = x

Let the large boxes = y

x + y = 30

6x + 8y = 210

6(30 - y) + 8y = 210

180 - 6y + 8y = 210

180 + 2y = 210

2y = 210 - 180

2y = 30

y = 15

x = 30 - 15

x = 15

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
