Answer:
Your answer will be C. $5.79.
Step-by-step explanation:
To get this answer, you have to take the original price (3.99) and multiply it by the mark up (45%)
3.99x0.45=1.79
Then, you add 3.99 and 1.79 to get your final answer.
3.99 + 1.79 = 5.78
The answer is off by one penny, BUT, it's tricky to get it exact when you're working with decimals and percentages.
