Question

A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. Each small box of paper weighs 50 pounds and each large box of paper weighs 80 pounds. A total of 19 boxes of paper were shipped weighing 1280 pounds altogether. Determine the number of small boxes shipped and the number of large boxes shipped

Answer 1

The number of small boxes is 8 and that of the large boxes is 11.

Step-by-step explanation:

Each small box of paper weighs 50 pounds and each large box of paper weighs 80 pounds. A total of 19 boxes of paper were shipped weighing 1280 pounds altogether.

Let there are x small boxes and y large boxes.

Then,

x + y = 19 ............ (1) and

50x + 80y = 1280

⇒ 5x + 8y = 128 ............... (2)

Now, solving equations (1) and (2) we get,

5( 19 - y) + 8y = 128

⇒ 3y = 128 - 95 = 33

⇒ y = 11

Now, from equation (1) we get, x = 19 - y = 19 - 11 = 8

Therefore, the number of small boxes is 8 and that of the large boxes is 11. (Answer)

Answer 2

Given :

• A paper company needs to ship paper to a large printing business.

ㅤㅤ

• The paper will be shipped in small boxes and large boxes.

ㅤㅤ

• Each small box of paper weighs 50 pounds and each large box of paper weighs 80 pounds.

ㅤㅤ

• A total of 19 boxes of paper were shipped weighing 1280 pounds altogether.

ㅤㅤ

Find :

• Determine the number of small boxes shipped and the number of large boxes shipped.

ㅤㅤ

Calculations :

• Let "S" be small boxes and "L" be large boxes.

ㅤㅤ

• Small box + Large box = 19
• 50S + 80L = 1280

ㅤㅤ

→ 5S + 8L = 128

→ 5 (19 - L) + 8L = 128

→ 3L = 128 - 95

→ L = 33/3

→ L = 11

ㅤㅤ

Finding the small box:

→ S = 19 - L

→ S = 19 - 11

→ S = 8

ㅤㅤ

Therefore ,

• Large boxes = 11.
• Small boxes = 8.
