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>
Let Ale’s money=a
Let Leo’s money=L
a=2L+3
You may have to rearrange any multiple choice answers algebraically, but they should all simplify down to the a= equation.
In problems like this, you can solve by thinking of how the word problem defines the variable. Ale is defined as twice Leo, plus three.

31=2y-5
Add 5 on both -5+5 which cancels out and 31+5 which is 36 and then divide 36 by 2 which equals to 18.
So y=18 hope this helped (':
