johnny bought an oil painting originally priced at $80 but on sale for 50% off. after 10% sales tax, what was the total cost?
Answer
Explanation:
Step1: Calculate the sale - price
The original price is $80 and it's 50% off. The sale - price is $80\times(1 - 50%)=80\times0.5 = 40$.
Step2: Calculate the total cost with tax
The sales tax is 10%. So the total cost is $40\times(1 + 10%)=40\times1.1=44$.
Answer:
44
