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