$86.825

Explanation:

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

Explanation:

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

Thus the total payment was:

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