Respuesta :

20% of $30 is $6.00 30 +6 = $36.00 + 5.75%(2.07) $36 + 2.07 = $38.07

Answer: The total is $37.73

Step-by-step explanation:

The manicure cost $30, and she wanted to give a tip of 20% (of the $30), and the taxi is 5.75% (again, of the $30).

so the total she spent is:

S = $30 + 0.20*$30 + 0.0575*$30 = $37.73

where the term with the 0.20 corresponds to the 20% for the tip, and the one with 0.0575 is the 5.75% for the tax.
