Tara's meal cost $8.60. She had to pay sales tax of 7%. Then she left a 10% tip based off the new total. What did she spend altogether?

\(860 \cdot \frac{100 + 7}{100} = 920.2\) (but you have to round it since you can't have fractional cents)

Now add the 10% tip:

\(920 \cdot \frac{100 + 10}{10} = 1012\)

Which means she spent $10.12 altogether :)
