Hey there!
We'll set up a proportion:
[tex] \frac{$20}{6} = \frac{1}{x} [/tex]
We can cross multiply:
20x = 6
DIvide both sides by 20
x = 6/20 = 30/100 = 0.30 cents.
Hope this helps

Answer:

$0.30

Step-by-step explanation:

The ratio of number of markers to cost of markers is 20:6

Let's find an equivalent ratio that shows the cost for 1 marker.

A ratio where one of the terms is 1  is called a unit rate. We can divide the number of markers by 20 to get to 1 markers

The cost of 1 marker is $0.30
