Your friend works as a waitress at a local restaurant. Her income consists of an hourly wage plus tips. On Wednesday, your friend earned $25 in tips over a 5 hour period. On Friday, your friend earned $30.76 in tips over a 3 hour period. How much is your friend’s hourly wage if your friend earned the same amount of money on Wednesday as on Friday?

Respuesta :

The total amount earned for both days are expressed as below.

 Wednesday:
               E = 5x + 25

Friday:
             E = 3x + 30.76

where x is the hourly wage. Equating both equations,

       5x + 25 = 3x + 30.76

The value of x from the equation is 2.88.

Answer: $2.88/hour
