Answer:
1. $67.72
2. It's correct.
Step-by-step explanation:
1.
bill: $68.89
discount: $10
tip: 15%
Calculate the total with the discount.
68.89-10=58.89
Now calculate 15% of that.
Convert 15% to decimal by dividing by 100
[tex]\frac{15}{100}=0.15[/tex]
Multiply
[tex]0.15(58.89)=8.83[/tex]
Add this to the original amount.
[tex]58.89+8.83=67.72[/tex]
----------------------------------------------------------------------------
Calculate 20% of 148.25
Convert 20% to decimals by dividing by 100
[tex]\frac{20}{100}=0.20[/tex]
Multiply
[tex]0.20(148.25)=29.65[/tex] This is how much they will tip.
Add this to the original bill;
[tex]148.25+29.65=177.90[/tex]
