Answer:
$2.48
Step-by-step explanation:
Let cost be c
So we can say 109% of the cost is the selling price.
109% means 1.09. Thus we can setup an equation to find the cost, c.
1.09c = 29.99
c = 29.99/1.09
c = 27.51
<em>The </em><em>markup is selling price - cost</em><em>, hence,</em>
<em>29.99 - 27.51 = </em><em>$2.48</em>
