How do you solve break even problems?

1 answer:

8 0

A break even problem is found when you calculate starting a buisieness
so lets ssay you have to buy 3 coppy machines and each machine costs 2000 dollars,
the people who want to use your coppy machines have to pay $0.40 per page
so you have spent 6000 dollars already
when you break even, it is when your earnings equals your expenditure (how much you earned equals how much you paid)

marysya [2.9K]

Answer:

179.5 - 180.5

Step-by-step explanation:

Time is a continuous variable. The minimum sleep time per night per subject here, is given as 1 minute.

Larger sleep times could be 1.08 minutes, 2.99 minutes, and other continuous/infinite values. Remember there are 60seconds in a minute and in-between seconds, there are milliseconds. So time is a continuous variable.

In this case though, our measurement of time is given in whole number units (integers). Our precision of measurement is 1 unit. We have an observed value of 180 minutes (the first subject's sleep time). The real limits of this value are 179.5 to 180.5

Savatey [412]

Answer:

52 ft

Step-by-step explanation:

area of a square is l x w. all sides are equal so the l = w

A = 169 ft^2 so each side is the square root of 169 which is 13 ft

perimeter of the floor would be all four sides added or length of 1 side multiplied by 4 since they are all equal

Perimeter = 13ft × 4 = 52 ft

so:

35% discount: 278.85

5% tax: $13.94

Final cost: 292.79

Step-by-step explanation:

regular price=$429

0.35(429)=150.15

429-150.15=278.85

35% discount amount: $278.85

278.85(0.05)=13.94

278.85+13.94=292.79

Luz earns $400 for 40 hours of work. Use a ratio table to determine how much she earns for 6 hours of work.

LiRa [457]

To work out how much Luz earns, you simply have to follow 400/40=10, so she earns $10/hour. We can therefore establish that if she works for 6 hours, she'll earn $60.

Can someone solve -192= -6 (6x - 4) step by step?

olasank [31]

Answer:

x= 4 2/3 OR 14/3 OR 4.6... –– 4 2/3 and 4.6... are the simplest form.

Step-by-step explanation:

Your original equation is -192 = -6 (6x - 4):

1. -192 = -6 (6x - 4)

Use distributive property and multiply: -6 x 6x = -36x and -6 x -4 = 24:

2. -192 = -36x + 24

We now move the +24 onto the other side of the equation, -192. Add 24 onto -192 and since we're moving the 24 on the left side of the equation, 24 will removed, so -24 on the right side of the equation:

3. -192 + 24 = -36x + 24 - 24

Divide both sides of the equations by -36 to get "x" by itself:

4. -168 / -36 = -36x / -36

Simplify the fraction of 24/36 by 12:

5. 4 24/36 = 4 2/3 or 14/3 or 4.6... = x

4 2/3, 14/3, 4.6... = x
