lindsey bought a picnic basket originally priced at $40 but on sale for 50% off. after 10% sales tax, what was the total cost? $ submit
Answer
Explanation:
Step1: Calculate the sale - price
The original price is $40 and it's 50% off. The sale - price is $(1 - 0.50)\times40$. $40\times(1 - 0.50)=40\times0.5 = 20$.
Step2: Calculate the total cost with tax
The sales tax is 10%. The total cost is the sale - price plus 10% of the sale - price, which is $20+(0.10\times20)$ or $20\times(1 + 0.10)$. $20\times(1 + 0.10)=20\times1.1=22$.
