Mariulka [41]

Answer:

Cost: $14.349

Markup: $15.649

Step-by-step explanation:

1. Rewrite the percent as decimal. Divide it by 100, as following:

 109/100=1.09

3. Now, knowing that Baby blankets sell for $29.99 after a markup rate based on cost of 109%, you can write the following expresion:

x+1.09x=29.99

Where x is the cost.

 4. You must solve for x, then, you obtain:

2.09x=29.99\\x=\frac{29.99}{2.09}\\x=14.349

5. The markup is:

M=29.99-14.349=15.649
