The total money was the whole meal($46.50) + 20% of the #$46.50#
The total money was #46.50+46.50xx20/100#
I wrote #20/100# because #20%# means #20/100#
#46.50+46.50xx20/100#
Convert the decimal into fraction as we are no calculators
#465/10+cancel465^93/10xx1/cancel5^1#
We are left with #465/10+93/10#
Add
#558/10#
#55.8#
The total cost for Madeline (sounds familiar to Adrenaline) was #color(red)($55.8#
