Answer 1

Take 8 times 7% and then take 8 time 15% add those numbers too $8 and you will find your answer. 7% = 7/100 and 15% = 15/100

Answer 2

Total cost $9.76 of Livia's lunch.

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
