Happy Store realizes a mark-up of PhP3,450 in selling TV sets. If its items are sold at a
Anna007 [38]

Answer:

Below is the answer.

Step-by-step explanation:

let s = the selling price.

the selling price presumably includes the cost plus the mark up plus the anticipated profit.

you have s = c + m + p

since m = 3450 and m = .4 * s, then you get:

.4 * s = 3450.

solve for s to get = 3450 / .4 = 8625.

your equation of s = c + m + p becomes:

8625 = c + 3450 + p

you don't know what p is supposed to be.

you don't know what c is supposed to be.

you need p to solve for c.

you need c to solve for p.

the best you can do is solve for c in terms of p, or solve for p in terms of c.

solving for c in terms of p gets you:

c = 8625 - 3450 - p which becomes c = 5175 - p

solving for p in terms of c gets you:

p = 8625 - 3450 - c which becomes p = 5175 - c.

you say that overhead expenses are 27% of the cost.

does this assume that overhead expenses are included in the cost.

regardless, if you don't know the cost, you can't solve for the overhead expenses.

i don't think you can solve this problem with the information given.

you might want to check to see if you're missing some information required to solve it.

A factor of 30 is chosen out random.what is the probability as a decimal,that is a two digit number.
goblinko [34]

Answer:

A factor of 30 is chosen at random. What is the probability, as a decimal, that it is a 2-digit number?

The positive whole-number factors of 30 are:

1, 2, 3, 5, 6, 10, 15 and 30.

So, there are 8 of them. Of these, 3 have two digits. Writing each factor on a slip of paper, then putting the slips into a hat, and finally choosing one without looking, get that

P(factor of 30 chosen is a 2-digit number) = number of two-digit factors ÷ number of factors

=38=3×.125=.375  as a decimal number.
