Ben and Cam are scuba diving. Ben is 15.815.815, point, 8 meters below the surface of the water. Cam is 4.24.24, point, 2 meters

alexira [117]

Answer:

Cam is at 6m below the surface of the water.

Step-by-step explanation:

Ignore all info except:

Ben is 8 meters below the surface of the water.

Cam is 2 meters above Ben

So now answer this;

What is Cam's position relative to the surface of the water?

This is too simple. Cam is 2 m above Ben which means two meter closer to the surface as Ben.

Ben was 8 m below the surface. By this Cam is 2 m closer to the surface, which is 8 - 2 = 6 m.

Cam is at 6m below the surface of the water.

A company sells its printers to customers in order to make a profit of 25% calculate the price the company paid for a printer wh

ioda

The company paid $2000 for the printer

Step-by-step explanation:

Let x be the price of the printer for which the company bought it.

If x is the price of printer, then 25% of x will be the profit made by the company.

That is:

0.25x

According to the statement,

The cost and profit earned by company are equal to 2500

So,

$x+0.25x = 2500\\1.25x = 2500$

Dividing both sides by 1.25

$\frac{1.25x}{1.25} = \frac{2500}{1.25}\\x = 2000$

Hence,

The company paid $2000 for the printer
