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?
Answer: 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.

A 324 -inch pipe is cut into two pieces. One piece is five times the length of the other. Find the length of the shorter piece.
Answer:
64.8 in
Step-by-step explanation:
The pipe is 324 in and you cut in in two. Since we know that one piece is five times the length of the other, we can make the equation 324=5x. Divide both sides by five gets us 64.8 = x.
To check our work, let's multiply 64.8 by 5. It does equal 324 so we are correct.
