Question

Lainey bought a set of 20 markers for $6

Answer 1

$0.30.

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 marker.

$6÷20=$0.30

The cost of 1 marker is $0.30

Answer 2

it would be 20 x 6 because 20 sets pf markers for 6 dollars each.
