Using proportions, it is found that she earned $943,000 from CD sales.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
The total amount involved in the sells and downloads are:
1.22 x 5 + 2.1 x 1 = 8.2 million.
She was paid 11.5% of that, hence:
0.115 x 8.2 = 0.943 million = $943,000.
She earned $943,000 from CD sales.

Answer:
it is 45
Step-by-step explanation:
677
Answer:
All
Explanation:
When an equation is in the form of y=kx, it displays direct variation, meaning that the y-intercept is 0. For example, take an equation in slope-intercept form, it has an equation of y=mx+b. Since there is no "b", in the form y=kx, that means that the line must pass through the origin, or (0,0)
Answer:
Exponential
Step-by-step explanation:
The change isn't constant for the volume, so it must be exponential.
Using quadratic regression, the equation is:
