Eli buys a robot priced at $283. If the sales tax is 10%, how much will Eli pay?

Answer: $311.3

Step-by-step explanation:

First, you want to find the sales tax of 10%. In order to do that, you need to convert 10% into a decimal which would be 0.10. Once you have this, you multiply it by the original amount of 283. This will result in 28.3. Now that you have the sales tax, add it to the original amount. ($283 + $28.3) This gives you your final answer of $311.30.
