Len and Kris had dinner in a restaurant. The dinner bill was $18.50.
They had to pay a 5% food tax and they left a 15% tip for the waiter.
What was the total amount they paid for dinner that night?
To calculate the total amount they paid for dinner, we need to add the dinner bill, the food tax, and the tip amount.
Step 1: Calculate the food tax
The dinner bill was $18.50 and they had to pay a 5% food tax. To calculate the food tax, multiply the dinner bill by the tax rate:
Food tax = $18.50 * 5/100 = $0.925
Step 2: Calculate the tip amount
The dinner bill was $18.50 and they left a 15% tip. To calculate the tip amount, multiply the dinner bill by the tip rate:
Tip amount = $18.50 * 15/100 = $2.775
Step 3: Calculate the total amount they paid
To calculate the total amount, add the dinner bill, the food tax, and the tip amount together:
Total amount = dinner bill + food tax + tip amount
= $18.50 + $0.925 + $2.775
= $22.20
Therefore, the total amount they paid for dinner that night was $22.20.
To find the total amount they paid for dinner, we need to calculate the food tax and the tip, and then add these values to the dinner bill.
1. Calculate the food tax:
The dinner bill was $18.50, and they had to pay a 5% food tax.
To find the amount of the food tax, multiply the dinner bill by 5% (or 0.05):
Food tax = $18.50 * 0.05 = $0.925 (rounded to the nearest cent)
2. Calculate the tip:
The dinner bill was $18.50, and they left a 15% tip.
To find the amount of the tip, multiply the dinner bill by 15% (or 0.15):
Tip = $18.50 * 0.15 = $2.775 (rounded to the nearest cent)
3. Add the dinner bill, food tax, and tip together to find the total amount they paid:
Total amount paid = Dinner bill + Food tax + Tip
Total amount paid = $18.50 + $0.925 + $2.775
Total amount paid = $22.20
Therefore, the total amount they paid for dinner that night was $22.20.
18.50 * 1.05 = $19.43
19.43 * 1.15 = $22.34
