Answer - Part A:

I would say "whole".

Step-by-step explanation:

So, it talks about the discount being 30% or $24 dollars. This is only part of the original price.

Where, the original price is the total price. So, the means that it is the whole price.

Just to help:

Answer - Part B: The original cost of the jeans are $80.

Step-by-step explanation:

If you find 30% of 80, then you will have to do x/80 = 30/100. Next, you will cross multiply (x times 100 and 80 times 30), which gives you 100x and 2,400. Now, you will divide both numbers by 100. You should now have x and 24. So, x = 24.

So, see? 30% of 80 is $24.

How is unit rate related to the linear equation?

Answers

Answer:

https://www.khanacademy.org/math/cc-eighth-grade-math/cc-8th-linear-equations-functions/cc-8th-graphing-prop-rel/v/graphing-proportional-relationships-example

Step-by-step explanation:

Answer:

A proportional relationship between two quantities is one in which the two quantities vary directly with one and other. If one item is doubled, the other, related item is also doubled. Because of this, it is also called a direct variation. The equations of such relationships are always in the form y = mx , and when graphed produce a line that passes through the origin. In this equation, m is the slope of the line, and it is also called the unit rate, the rate of change, or the constant of proportionality of the function.
