Allisa [31]

Answer:

Step-by-step explanation:

Answer:

4,923.75ft²

Step-by-step explanation:

The area of the backyard = Length * width \

Area of the backyard = 75 3/4 * 81 1/4

Area of the backyard = 303/4 * 325/4

Area of the backyard = 6,154.6875ft²

If 3/4 of the fence is finished, the area of the finished part is expressed as;

Finished part = 1/5 * 6,154.6875

Finished part = 1,230.9375ft²

Part left unfinished = 6,154.6875-1,230.9375

Part left unfinished = 4,923.75ft²

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
