The salary difference between men over 25 years old and men 16~24 years old is \$330. If men over 25 make \$722 per week, how much do men between 16 and 24 make per week? The answer: Definitions: x = weekly salary for men over 25 years old y = weekly salary for men 16 to 24 years old x – y = 330 x = 722 To solve for y (weekly salary for men 16 to 24 years old), substitute 722 for x in the first equation: 722 – y = 330 Add y to each side of the equation: 722 – y + y = 330 + y 722 + 0 = 330 + y 722 = 330 + y Subtract 330 from each side of the equation: 722 – 330 = 330 – 330 + y 392 = 330 – 330 + y 392 = 0 + y 392 = y The final answer is: the weekly salary for men 16 to 24 years old = \$392 Thanks for writing.
