A couple goes out to dinner, which costs $45. To the nearest dollar, what should they pay in total, if they tip 15% on the bill?
Here are the options,
(1) $45
(2) $50
(3) $51
(4) $52
(5)$ 53
--------------------
The answer I choose is (3). Can someone check if I got the answer right, and if I could have the right answer.
A couple will pay 100% + 15% = 115%
115% = 115 / 100 = 1.15
1.15 • $45 = $51.75
To the nearest dollar, they pay in total $52 because different betwen $52 and $ 51.75 is $0.25
Different betwen $51.57 and $ 51 is $0.75
$ 52 is closer to $ 51.75 than $ 51
Answer (4)
15% of 45 is 6.75 so in order to get 115% you would take 45 and 6.75 and add them to get 51.75 and if you round that to the nearest dollar you get 52
Thanks,.
Well, let's do some math and find out if you got it right!
The tip is 15% of $45, so we can calculate it as follows:
$45 x 0.15 = $6.75
Now, let's add the tip to the original bill amount:
$45 + $6.75 = $51.75
To the nearest dollar, the couple should pay $52 (option 4). So, it looks like you were just a tad off with your answer. But hey, close enough! Keep up the good work, and remember, math and tipping can sometimes be as tricky as juggling flaming rubber chickens on a unicycle!
To find the total amount the couple should pay, you need to add the cost of the dinner and the tip amount.
To calculate the tip, you can multiply the bill amount by the tip percentage (15%), and then add this tip amount to the bill amount.
Let's calculate:
Tip amount = 15% of $45
Tip amount = (15/100) * $45 = $6.75
Total amount to pay = Bill amount + Tip amount
Total amount = $45 + $6.75 = $51.75
To round to the nearest dollar, you will round down if the decimal part is less than 0.5, and round up if the decimal part is 0.5 or greater.
In this case, the decimal part of $51.75 is 0.75, which is greater than 0.5. Therefore, you round up.
Rounded total amount = $52
So, the correct answer is (4) $52.
You chose (3) $51, which is not the correct answer.
