Question

If 8 markers cost $20 what is the cost of 12 markers

Answer 1

$30

Explanation:

Find the cost per marker.

Given: 8 markers = $20

Divide 8 from both sides.

Let x = amount of markers.

(8x)/8 = (20)/8

x = 2.5

Each marker costs $2.50

Now, multiply 12 with $2.50

2.50 x 12 = 30

$30 is the cost of 12 markers.
