8. Your meal at a local restaurant is $12.45. Tax
is 6% and you tip 18%.
What is your final cost?

Around $15.44

Step-by-step explanation:

12.45 + (12.45*0.06) + (12.45*0.18) = 15.438

First we need to find a formula.

(12.45+6%)+18%

6 percent of 12.45 is equal to 0.75, approximately. (0.747)

0.75+12.45=13.2

13.2 plus a tip of 18%

18% of 13.2 is 1.06.

13.20+1.06=14.26

the final cost is 14.26
