Answer:
$340
Step-by-step explanation:
Given:
Jim is paid 17% for every ad he sells.
He sold an ad today for $2000
Now we have to find the commission.
The commission rate is 17%
If he sells $100, then he gets $17 as commission.
To find the commission on sale ad of $2000, we have to multiply 2000 by 17%
17% of 2000
=
We can simplify 2000 by 100, we get
= 17*20
Commission = $340
He gets $340 as commission for the ad sale of $2000.
A system of equations with infinitely many solutions is a system where the two equations are identical. The lines coincide. Anything that is equal to 
will work. You could try multiply the entire equation by some number, or moving terms around, or adding terms to both sides, or any combination of operations that you apply to the entire equation.
You could multiply the whole thing by 4.5 to get
. If you want, you could mix things up and write it in slope-intercept form: 
. The point is, anything that is equivalent to the original equation will give infinitely many solutions x and y. You can test this by plugging in values x and y and seeing the answers!
The attached graph shows that four different equations are really the same.
