Answer: the total cost of the nightstand is $22
Step-by-step explanation:
The original price of the night stand is $50. If the original price of the night stand was marked down by 60%, it means that the amount of money by which it was reduced would be
60/100 × 50 = 0.6 × 50 = 30
The new selling price would be
50 - 30 = $20
If she paid 10% sales tax,the amount of tax paid would be
10/100 × 20 = 0.1 × 20 = 2
Therefore, the total cost of the nightstand would be
20 + 2 = $22
