Rick took his family out for dinner. he planned to leave a 15% gratuity on the bill. what is the total cost of the bill is 123.50$?

142.03 would be your answer

Step-by-step explanation:

You can multiply 123.50 by 15, which gets you $1852.50. Divide that by 100 and you are left with $18.525, which you can round to $18.53. Add that to what the cost of the bill was and you are left with $142.03

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

true? is that what you're asking or do you mean something else?
