Answer:
$52.73
Step-by-step explanation:
Total Cost is sum of the individual costs
Total cost of food is [tex]12.99+25.98+4.29=43.26[/tex]
Now, adding 6% sales tax on top of that is:
[tex]43.26*(1.06)=45.8556[/tex]
Then, 15% tip on top of that:
[tex]45.8556*1.15=52.73[/tex]
Hence total cost of restaurant outing is $52.73
