An instructor makes $15 more per hour than an assistant. If the combined hourly wage of the instructor and assistant is $65, wha
t is the hourly wage of the assistant? A. $15 B. $20 C. $25 D. $30
1 answer:
X= assistant's wage
x+15= instructor's wage
Add their wages set equal to $65
x + (x + 15)= 65
combine like terms
2x + 15= 65
subtract 15 from both sides
2x= 50
divide both sides by 2
x= $25 assistant's wage
x+15= 25 + 15= $40 instructor's wage
ANSWER: (C) $25 hourly wage of assistant
