Question

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?

Answer 1

Answer:

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

Answer 2

Answer:

15

Step-by-step explanation:

Call the number of small boxes  and the number of large boxes . We can use the following system of equations to represent the information given: Multiplying the first equation by 6 and subtracting the result from the second equation yields Solving for  gives , or . Thus,  large boxes were sent.
