Luisa's restaurant bill comes to $75.50, and she leaves a 15% tip. What is Luisa's total payment?

Answer 1

#$86.825#

To obtain the tip, you multiply the restaurant bill by the percent increase that is #15%# (or #0.15#), then you add the actual bill to the tip to determine the total restaurant bill.

#"tip" = $75.5xx0.15 = $11.325#

#"total restaurant bill" = $11.325 + $75.5= 86.825#

#$86.83#

The % symbol is like a unit of measurement but one that is worth #1/100#. Consequently 15% #->15xx1/100=15/100#

As such the tip is #15/100xx$75.50 = $11.325#

Rounding this to the nearest 2nd decimal place gives: #$11.33#

Consequently, the entire amount paid was:

#$75.50# #ul($11.33 larr" Add")# #$86.83#
