Final answer:
After applying a 10% discount to a $15.50 lunch total and adding a 6.35% Connecticut sales tax, the final amount to be paid is $14.84.
Step-by-step explanation:
To calculate the total amount you have to pay for lunch, including a 10% off coupon and a Connecticut sales tax of 6.35%, follow these steps:
- Calculate the discount amount by converting 10% to a decimal (0.10) and multiply it by the total cost, which is $15.50:
$15.50 × 0.10 = $1.55. - Subtract the discount from the total cost to get the discounted total:
$15.50 - $1.55 = $13.95. - Now, find the amount of sales tax by converting 6.35% to a decimal (0.0635) and multiply it by the discounted total:
$13.95 × 0.0635 = $0.885525, which can be rounded to $0.89. - Add the sales tax to the discounted total to get the final amount you have to pay:
$13.95 + $0.89 = $14.84.
Therefore, the total amount you have to pay after applying the 10% off coupon and adding 6.35% sales tax is $14.84.
