Answer:
Yes, there is a constant of variation
Step-by-step explanation:
Let's see, we have a linear equation that is as follows:
<em>y = 26.2 * x.
</em>
The first thing is to say that there is a constant of variation and it is the constant number of the equation, that is 26.2. And second to mention that it is the reason (or quantity, whether proportional or direct) for which the input data (i.e. x) and the output data (i.e. y) vary.
If the original price is x, then x-0.10x=0.9x (which is a 10 percent off discount - 10 percent = 0.10 if you move the decimal spot 2 places over), then 10% of 0.9x is not 0.10x due to that 0.1/0.9=1/9, not 1/10. 1/10 of 0.9 is 0.09, so
0.9-0.09=0.81 of the original price
If the 10% sales tax was added first, it wouldn't matter since you're still getting 10% twice either way
