Jay makes a base salary of $2000 per month. Once he reaches $50000 in total sales, he earns an additional 5% commission (salary)
ki77a [65]

Answer:

j(s) = 0.05s -500

Step-by-step explanation:

Given

Base\ Salary = 2000

Commission = 5\% on Sales over 50000

Required

Determine the function j(s) for sales over 50000

Represent the total sales in a month with s.

Sales over 50000 in that month will be: s - 50000

So, the function j(s) is:

j(s) = Base Amount + Commission * Sales over 50000

j(s) = 2000 + 5\% * (s - 50000)

Convert % to decimal

j(s) = 2000 + 0.05 * (s - 50000)

Open bracket

j(s) = 2000 + 0.05 * s - 0.05 * 50000

j(s) = 2000 + 0.05s - 2500

Collect Like Terms

j(s) = 0.05s - 2500 + 2000

j(s) = 0.05s -500

The radius of a circle measures 15 ft. What is the circumference of the circle?
Pie

Answer:

\boxed {\tt 94.2 \ feet}

Step-by-step explanation:

The circumference of a circle can be found using the following formula:

c= \pi d

where d is the diameter. We are given the radius, so let's find the diameter.

The diameter is twice the radius.

d=2r

The radius is 15 feet.

d= 2 * 15 \ ft

Multiply.

d= 30 \ ft

Now we know the diameter. Substitute 30 feet in for d.

c= \pi d

c=\pi * 30 \ ft

We are using 3.14 for pi, so substitute it in.

c=3.14 * 30 \ ft

Multiply.

c= 94.2 \ ft

The circumference of the circle is 94.2 feet.

The conversion of 9.204 to a mixed number will be 9 51/250.

<h3>How to illustrate the information?</h3>

It should be noted that converting decimal to mixed numbers simply means changing them to whole numbers and fractions.

Therefore, 9.204 will be:

= 9 204/1000

= 9 51/250

The percentage equivalent of 3 7/8 will be:

= (3 × 100) + (7/8 × 100)

= 300 + 87.5

= 387.5%

Dividing 72 in the ratio 2:3:4 will be:

= 2/9 × 72 = 16

= 3/9 × 72 = 24

= 4/9 × 72 = 32
