the sales tax rate is 10%. if lindsey buys a television priced at $686, what will be the total cost including tax?
Answer
Explanation:
Step1: Calculate the tax amount
The tax rate is 10% or 0.1. The tax amount is 10% of the price of the television. So, the tax amount $T = 0.1\times686$. $T=0.1\times686 = 68.6$
Step2: Calculate the total cost
The total cost $C$ is the sum of the price of the television and the tax amount. So, $C=686 + T$. $C=686+68.6=754.6$
Answer:
$754.6$
