Total cost $9.76 of Livia's lunch.

Step-by-step explanation:

Livia's bill for lunch came = $8.00

The restaurant included a 7% sales tax =  7% of $8.00

= 0.07 × 8 = 0.56

She left a tip of 15% = 15% of $8 =

= 0.15 × 8 = $1.20

Now add tip and tax to the lunch bill

Bill (Pre tax) = $8.00

Tax 7%        = $0.56

Tip 15%       = $1.20

= 8.00 + 0.56 + 1.20 = $9.76

Total cost of Livia's lunch was $9.76
