Answer: B

<u>Step-by-step explanation:</u>

Use the distance formula: d = \sqrt{(x_2 -x_1)^{2}+(y_2-y_1)^{2}}

d_{PQ} = \sqrt{(8-4)^{2}+(1-4)^{2}}

         = \sqrt{(4)^{2}+(-3)^{2}}

         = \sqrt{16+9}

         = \sqrt{25}

         = 5

A little shop sells Christmas toys. The wholesale price for each toy in a consignment of 50 toys was $5.5. Half of this quantity
laila [671]

Answer:

Profit = \$250

Step-by-step explanation:

Given

Number of Toys = 50

Unit Cost Price = $5.5

Unit Selling price = $15

Required

Determine the profit after sales

First, we need to determine the total cost price;

Cost\ Price = Number\ of\ toy *\ Unit\ cost\ price

Cost\ Price = 50 * \$5.5

Cost\ Price = \$275

First, we need to determine the total sales;

____________________________________________________

Half of the toy was sold at $15;

Half\ of\ the\ toy = \frac{1}{2} * 50

Half\ of\ the\ toy = 25

Sales = \$15 * 25

Sales = \$375

____________________________________________________

Two-fifth of the remaining was sold at half of the sales price

From the above calculation;

Remaining\ Toy = 50 - 25

Remaining\ Toy = 25

<em></em>

<em>Calculating Two-fifth of the remaining:</em>

\frac{2}{5} * 25

= \frac{50}{5}

= 10

<em>Calculating half of the sales price:</em>

\frac{1}{2} * \$15

\$7.5

This means that 10 toys were sold for $7.5

Sales = 10 * \$7.5

Sales = \$75

____________________________________________________

The remaining was sold at one-third of the sales price

From the above calculations (1 & 2);

Remaining\ Toy = 50 - 25 - 10

Remaining\ Toy = 15

<em>Calculating </em>one-third <em>of the sales price:</em>

\frac{1}{3} * \$15

\$5

This means that 15 toys were sold for $5

Sales = 15 * \$5

Sales = \$75

____________________________________________________

Now the total sales can be calculated;

Total\ Sales = \$375 + \$75 + \$75

Total\ Sales = \$525

Profit = Total\ Sales -\ Cost\ Price

Profit = \$525 -\$275

Profit = \$250
