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>
Answer:
k = 4
Step-by-step explanation:
Rearrange so that like terms are on either side of the equation
4k - 2k - 2k + 2k = 5 + 3
Simplify
2k = 8
Divide both sides by two to make k on its own
k = 4
You are correct, well done!
