insens350 [35]

Answer:

So Average Price of horse is $360

Step-by-step explanation:

Given:

25 horses sold in January for $ 2500

25 horses sold in February for $10500

TO find:

Average price of horse = ?

Solution:

Average price is usually found out by adding all the values and dividing by its total no of values

Now in our case

Total Horse = 25 + 25

                     = 50

Total Money = $7500 + $10500

                      = $18000

Average Price =\frac{total price}{total horses}

Average Price =\frac{18000}{50}

                                =$360

So Average Price of horse is $360

F) The marked price of a radio is 25 % above the selling price and the cost pr
Ostrovityanka [42]

Answer:

See explanation below.

Step-by-step explanation:

Let's say, x represents the sale price of radio.

Then the marked price of the radio is 1.25x

The cost price of the radio is (1.25x)(0.70)

The discount is simply 25% because the radio is being sold at 25% less then the marked price.

The gain percent is given as:

\frac{x-1.25x\times \:0.70}{x}\times 100\\\\=12.5\%

The radio is being sold at 12.5% gain.

Best Regards!
