Solution:
The cost for Dana and Courtney's lunch is $24
They want to leave a 15% tip
To find: total cost of their lunch, including the tip
Find the tip amount
Tip amount = 15 % of 24
[tex]Tip\ amount = \frac{15}{100} \times 24\\\\Tip\ amount = 0.15 \times 24\\\\Tip\ amount = 3.6[/tex]
what is the total cost of their lunch, including the tip?
Total cost = cost of lunch + tip amount
Total cost = 24 + 3.6
Total cost = 27.6
Thus total cost of their lunch, including the tip is $ 27.6
