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

$Tip\ amount = \frac{15}{100} \times 24\\\\Tip\ amount = 0.15 \times 24\\\\Tip\ amount = 3.6$

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
