A company manufacturer two types of printers, an inkjet printer and a laser printer. The company can make a total of 60 printers
myrzilka [38]

Answer:

30 inkjet printers

30 laser printers

Step-by-step explanation:

Let x be inkjet printer

Let y be the laser printer

Total printer produced per day = 60

This implies that x+y = 60

The company has 120 labor hours per day. If it has 1 labor hour to make a inkjet printer and 3 labor hours to make a laser printer, we will have

x + 3y = 120

So we have

x + y = 60 ........(1)

x + 3y = 120 ........(2)

Subtract equation 1 from 2

We have

2y = 60

y = 60/2

y = 30

Put y= 30 into equation 1

x + y = 60

x + 30 = 60

x = 60 -30

x = 30

Therefore we have 30 inkjet printers and 30 laser printer.

Suppose a group of x people rent a jeep for $80 for a trip to the beach and plan to share the cost equally. If one person in the
yarga [219]

Answer:

Step-by-step explanation:

Given that a group of x people rent a jeep for 80 dollars.

Since they share the amount equally we have

each person share =\frac{80}{x}

When one person in the group decides not to go, each remaining person has to pay an extra 4 dollars.

i.e. now the share borne by each in the group would be

\frac{80}{x-1}

This is 4 dollars more than the original

Hence equation would be

\frac{80}{x-1}-\frac{80}{x} =4

This equation would be used to determine how many people are in the group.
