Mrs.Margul paid $125 to have her hair colored and cut if she tips her hairdresser 15% what is her total bill

pantera1 [17]

Answer:

143.75

Step-by-step explanation:

The tip is the cost times the tip rate

tip = cost * rate

The cost is 125 and the rate is 15%

tip = 125 * 15%

Change this to decimal form

tip = 125 *.15

= 18.75

The total bill is the cost plus the tip

total bill = cost + tip

= 125 + 18.75

= 143.75

What is the value of x?<br><br><br><br> Enter your answer in the box.

OverLord2011 [107]

5x + 10 10
---------- = -------
121 11

make the bottom have same common denominator

10/11 x (10/10) = 100/121

Get rid of the denominator (for both now have 121 as a base)

5x + 10 = 100

5x + 10 (-10) = 100 (-10)

5x = 90

5x/5 = 90/5

x = 18

x = 18 is your answer

hope this helps
