Final answer:
To find the maximum number of candles Edwin can buy, divide the amount of money he has by the cost of each candle. The maximum number of candles Edwin can buy is 9. The total cost of the candles, including sales tax, is $124.02.
Step-by-step explanation:
To find the maximum number of candles Edwin can buy, we need to divide the amount of money he has by the cost of each candle.
Edwin has $120 to spend and each candle costs $13. Let's calculate:
- Divide $120 by $13 to find the maximum number of candles Edwin can buy: 120 / 13 = 9.23.
- Since Edwin can't buy a fraction of a candle, he can only buy a whole number of candles. Therefore, the maximum number of candles Edwin can buy is 9.
- Now, let's calculate the total cost of 9 candles: 9 x $13 = $<<9*13=117>>117.
- Finally, let's calculate the sales tax: 6% of $117 = $<<117*0.06=7.02>>7.02.
- Add the sales tax to the total cost of the candles: $117 + $7.02 = $<<117+7.02=124.02>>124.02.
Therefore, Edwin can buy a maximum of 9 candles.
