Inventory Heung-Soo is responsible for checking a shipment of technology equipment that contains laser printers that cost $700 e
Alla [95]

Answer:

P + M = 30

700P + 200M = 15000

Number of laser printers = 18

Number of color monitors = 12

Step-by-step explanation:

Let P = number of laser printers

Let M = number of color monitors

Given total number of boxes = 30

⇒ P + M = 30

Given:

  • $700 = cost of laser printer
  • $200 = cost of color monitor
  • $15000 = total cost of order

⇒ 700P + 200M = 15000

Rewrite P + M = 30 to make P the subject:

⇒ P = 30 - M

Substitute into 700P + 200M = 15000 and solve for M:

⇒ 700(30 - M) + 200M = 15000

⇒ 21000 - 700M + 200M = 15000

⇒ 500M = 6000

⇒ M = 12

Substitute found value for M into P = 30 - M and solve for P:

⇒ P = 30 - 12 = 18

jim is standing beside apool.He drops a weight from 4 feet above the surface of the water pool.The weight travels a total distan
Taya2010 [7]
<span>Treat the surface of the water as 0. The initial height of the weight was 4 ft above the surface of the water, therefore making it have an initial height of +4. If it travels 12 ft downward to hit the bottom of the pool, that means its height decreased by 12, so its falling is -12. To calculate the depth of the pool, use initial height minus drop distance, so 4 - 12. The depth of the pool is 8 ft.</span>
