The cost is 284 the operating expenses are 43 the reduced price is 299 what is the operating loss
NISA [10]

Answer:

28

Step-by-step explanation:

operating loss is loss when value of operating loss is more than gross profit.

In the given problem

cost: 284

price : 299

profit = 299 - 284 = 15

but given that there is operating expense as well.

operating expenses = 43

as expense is greater than profit there is loss which is called operating loss.

operating loss = operating expense - profit = 43 - 15 = 28

Thus, operating loss is 28.

A box contains a collection of triangular and square tiles. There are 2525 tiles in the box, containing 8484 edges total. How ma
AnnyKZ [126]
Let us consider the number of edges = x
we know that a triangle will have 3 edges and a square will have 4 edges. Using this details we can form an equation.
3x + 4x = 8484
7x = 8484
x = 8484/7
  = 1212
Then
Number of square tiles = 1212/4
                                     = 303
So there are 303 square tiles in the box. I hope the procedure is clear enough for your understanding. You can always use this method for solving similar problems.
