Cost price=38 and profit 15%find the selling price and profit​
shutvik [7]

Selling price (S) = 43.7

Profit = 6.7

Explanation:

Given parameters:

Cost price = 38

Profit = 15%

Unknown:

Selling price = ?

Profit = ?

Solution:

The selling price is the amount a particular good is sold.

  Selling price = Cost price + profit

The profit is the gain on goods sold.

    Profit = Selling price - cost price

We have been given the profit percent;

   %Profit = \frac{S.P - C.P }{C.P }  x 100

 15 =  \frac{S - 38}{38 }  x 100

 

  Selling price (S) = 43.7

 Profit = selling price - cost price = 43.7 - 38.00 = 6.7

il63 [147K]

Answer:

There are no options to this question, however, the question can be answered. The answer is:

FF and FF/Ff

Explanation:

This question involves a single gene coding for possession or not of freckles in humans. The allele for freckles (F) is dominant over the allele for no freckles (f). This means that genotypes FF and Ff (heterozygous) will possess freckles while only genotype ff will not.

According to this question, a couple has several children in which all of the children have freckles i.e. have either genotype FF or Ff. This is as a result of the fact that the parent's genotypes were either FF or Ff. That is, one parent is FF while the other is either FF or Ff. This genotypes will only produce children with freckles.
