If you sell 30 items at $200 a piece and your commission rate is 20%, how much commission do
jarptica [38.1K]

Answer:

$1200

Step-by-step explanation:

There are 2 ways I immediately think about to solving the problem.

1) You multiply 30 and 200 , then multiply the product by .2 (i.e. 20%)

This way, you'll find out what the total amount was($6,000), then you multiply it by your commission rate.(.2 or 20%) to find your total profit($1,200).

2) You multiply 200 by .20 , then multiply the product by 30.

This way, you'll find out what your commission would be for a single item($40), then multiply by the total items sold (30) to find your total profit($1,200).

What is the coordinate of point Z after translating it 7 units down and then translating it 8 units right
Diano4ka-milaya [45]

Using translation concepts, the coordinates of Z(x,y) after translating it 7 units down and then translating it 8 units right is:

Z'(x + 8, y - 7).

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

For this problem, the translations are given as follows:

  • 8 units right, hence x -> x + 8.
  • 7 units down, hence y -> y - 7.

Hence the coordinates of Z(x,y) after translating it 7 units down and then translating it 8 units right is:

Z'(x + 8, y - 7).

Factor quadratic trinomials 27x^2-90x+27
igor_vitrenko [27]
27x^2-81x-9x+27      In this case, just in your mind multiply 27 (coefficient of x^2) by the constant value 27(the end value of the quadratic trinomial). Then find factors that give you the value -90 when you add and 729 (27*27) when you multiply.

Factorise the values
 27x( x-3)-9(x-3)

Which will give you

(27x-9)(x-3)
