20. Rafael has a business selling computers. He buys computers from the manufacturer for $450
each and sells them for $800. Each month, he must also pay fixed costs of $3000 for rent and
utilities at his store. If he sells n computers in a month, which of the following equations can be used
to calculate his profit?
A. P = n(800 - 450)
B. P = n(800 - 450 - 3000)
C. P = 3000n(800 - 450)
D. P = n(800 - 450) - 3000
E. P = n(800 - 450) + 3000
Yeah
Answer: D , p = n (800 - 450) - 3000
Step-by-step explanation: Firstly, you have to account for how much money Rafael is making off of each computer (800 - 450). That factor is then multiplied by the variable "n" which represents the amount of computers sold. Lastly, since this is an equation to calculate his monthly profits, you have to subtract the rent that he is paying ($3000) from the total profit that he made off of selling the computers. Therefore, giving you the equation
P (profit) = n (amount of computers sold) (800-450) - 3000 (rent).
The equation that represents Rafael's monthly profit selling 'n' numbers of computers is D. P = n(800 - 450) - 3000.
What is an equation?An equation represents equality for the terms that are on the both side of the equal sign.
Given Rafael buys computers for 450 dollars and sells them for 800 dollars each.
He also had to pay 3000 dollars for rent and utilities for the store and the number of computers sold in each month is given by 'n'.
∴ The equation that represents his profit(P) in a month is,
P = n(800 - 450) - 3000.

what is a linear equation that is perpendicular to y=5
help please due soon
Answer:
y = 6x
Step-by-step explanation:
You can easily find the slope by using slope formula:
(y2-y1) / (x2-x1) (the numbers are subscript)
E.g: (24-12) / (4-2) = 12/2 = 6
m(slope) = 6

how to write an equation
Answer:
Step-by-step explanation:
An equation is like a sentence, just using a different language. Mathematical equations are telling you to do something, giving you information on how to respond, or come up with an answer. It's up to you to learn this language. However, once you know it, you can write in this language! You, too, can write algebraic equations.
Parts of a Mathematical Equation
A mathematical equation, also known as a statement, shows that two separate expressions are equal. The two expressions are usually connected by the "equal-to" (=) sign. You can find the expressions in a mathematical statement by looking at the left-hand side and the right-hand side of the equation, using the = sign as the point of reference.
Example: 2x + 3 = 11
It can be helpful to view equations as a scale in which weights are used to keep it balanced. The scale is balanced when what is placed on the right-hand side is equal in weight to what is on the left-hand side. Solving an equation can also be thought of in terms of adding weight to the left or right-hand side of the scale to balance it out.
Finding the solution to the equation involves manipulating the weights. Whatever is done on the right-hand side of the scale must also be done on the left-hand side to keep the scale balanced.
Your tools for this happen to be, most commonly, addition, subtraction, multiplication, or division.
Answer:
An equation uses symbols and numbers there are SO many equations you could make for example an easy one 6 x 5 = 30 there are two numbers you multiply to get a product. Whenever you write an equation you always put an equal sign which is this: = . This shows what you get from the equation. There are main parts the =, +, -, x, ÷ . All represent what you do to the two numbers you put on both sides of it.
