Answer:
the approximate markup rate on the dishwasher is $460
Explanation:
The sticker price on dishwasher = $1100
The amount paid by Natalia for two years = $15 per week
Now, 1 year ≈ 52 weeks
So, amount paid by her in 1 year = $ 15 x 52 weeks
= $780
⇒The amount paid in 2 years = 2 x $ 780 = $1,560
Now, the Marked up rate of the dishwasher = Selling Price - Cost
= $1,560 - $1100 = $460
Hence, the approximate markup rate on the dishwasher is $460.
