Question
Your friend works as a waitress at a local restaurant. Her income consists of an hourly wage plus tips. On Wednesday, your frien
d 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?
Solutions
Answer1
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
