He price of a shampoo, cut, and style at the hairstyling salon where you work is $18.00. You generally get a 20% tip from each c
Marianna [84]

Answer:

total earning is  $64.80

Step-by-step explanation:

Price of one work = $18.00

Payment  by owner = 1/4 of $18.00

                                 = 18/4

                                  = $4.50

Earning by tip =  20% of $18.00 =  20/100 x18 = 3.60

Total earning from one work   =   $4.50+$3.60

                                                = $ 8.10

Earning from 8 tips =  8x8.10

                                = $64.80

At school athletic events you can buy 3 drinks and 2 hot dogs for $4.80 or you can buy 1 drink and 1 hot dog for $2.00. How much
mariarad [96]
Let the cost of each drink is $x and the cost of each hot dog is $y.
According to the given data, 3 drinks and 2 hot dogs cost $4.80. In equation form, we can write it as:

3x+2y=4.80

1 drink and 1 hot dog costs $2.00. In equation form, we can write it as:

x+y=2
x=2-y

Using this value of x in first equation, we get:


3(2-y)+2y=4.80 \\ 
6-3y+2y=4.80 \\ 
6-y=4.80 \\ 
y=6-4.80 \\ 
y= 1.20

Thus the cost of one hot dog is $1.20
