Gail has $100 and wants to have her hair styled for the prom. The salon charges $56 for a hair styling. Gail plans to leave a 20% tip. In dollars, how much money will she have left after she pays the hair stylist?

She has left $32.8 after she pays the hair stylist.

Step-by-step explanation:

Money Gali has = $100

Charge per hair style = $56

Tip percent = 20%

Total charge for hair styling = Charge per hair style + Tip

= $ (56+ 20% of 56)

= $ (56+0.2 x 56)

= $ (56+11.2)

= $ 67.2

Money left = Money Gali has - Total charge for hair styling  

= $ (100-67.2)

= $ 32.8

Hence, she has left $32.8 after she pays the hair stylist.
