Answer:

<h2>Yes, the circumference will always double when the radius is doubled</h2>

Simple Explanation: For example, 2 is the given radius, we can double 2 and get 4 as our diameter, then times pi. We get 4 pi as our initial circumference.

When we double the radius, we have a given radius of 4, and to find the diameter we get 8. 8 times pi= 8 pi. This is the simple version of the below example

Full Example:

Radius - 3

Pretend the radius is 3, do 3*2 and get the diameter of 6, then times 3.14 equals 18.84. So the current circumference is 18.84.

Now to find the new circumference. Now the radius is 6. To find the diameter we can do 6*2 and get 12. Now to find circumference; 12 x 3.14 = 37.68. 37.68 / 18.84 = 2

<h3>What are linear equations?</h3>

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

<h3>How to determine the solution to the system?</h3>

A system of linear equations is a collection of at least two linear equations.

In this case, the given parameters are:

Guarantee fee = $250 per week

Commission = 15%

Let the total sales be x and the total amount be y

So, we have:

y = Guarantee fee + Commission * x

This gives

y = 250 + 15% * x

The total sales is $2050

This gives

y = 250 + 15% * 2050

Evaluate

y = 557.5

Hence, Piper would make $557.5 in a week in which she made $2050 in sales
