Step-by-step explanation:

✓ Step-by-step explanation:commission earned = 60% of $800800 × 60/100 = $480

The Commission (in dollars) he earn last month is $480.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

A salesman earns 60% commission on all the merchandise that he sells. Last month he sold $800 worth of merchandise.

So, the Commission he earns

= 800 + 800 x 60%

= 800 + 800 x 60/100

= 800 + 480

= 1280

Hence, the commission is $480.

Answer:

Step-by-step explanation:

Empty

5/8 * 160 = 100

Full

There are two ways you can do this.

160 - 100 = 60 seats were full

or

160 * 3/8 = 60 seats were full.

Where did the 3/8 come from?

1 - 5/8 = 3/8

Answer:

Step-by-step explanation:

Intersecting lines make equal opposite angles

2x + y = 50 - y

     2x = 50 - 2y

       x = 25 - y

A straight line represents 180°

4x + 6y + 2x + y + 2x + 3y = 180

                            8x + 10y = 180

                  8(25 - y) + 10y = 180

                  200 - 8y + 10y = 180

                                     2y = -20

                                       y = -10

       x = 25 - (-10)

       x = 35

Using the combination formula, it is found that there is a 0.2448 = 24.48% probability that the six claims selected will include one workers compensation claim, two homeowners claims and three auto claims.

Combination formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The desired outcomes are:

Thus:

[tex]D = C_{2,1}C_{4,2}C_{7,3} = \frac{2!}{1!1!} \times \frac{4!}{2!2!} \times \frac{7!}{4!3!} = 420[/tex]

For the total outcomes, six claims from a set of 13, thus:

[tex]T = C_{13,6} = \frac{13!}{6!7!} = 1716[/tex]

The probability is:

[tex]p = \frac{D}{T} = \frac{420}{1716} = 0.2448[/tex]

0.2448 = 24.48% probability that the six claims selected will include one workers compensation claim, two homeowners claims and three auto claims.
