Answer:
The total price including the tip is 69.60 $ and just the tip is 11.6 $.
Step-by-step explanation:
The total price including the tip is calulated by multiplying the bill by the decimal of the percent of the tip plus 1.
58 × 1.20 = 69.60 $
To get just the tip we can multiply the bill by just the decimal of the percent of the bill.
58 × 0.20 = 11.6 $
