Question 686813
Let {{{ x }}} = the hourly rate of the apprentice in dollars/hr
{{{ x + 25 }}} = the hourly rate of the plumber in dollars/hr
given:
{{{ 40x + 40*( x + 25 ) = 2600 }}}
{{{ 40*( x + x + 25 ) = 2600 }}}
{{{ 2x + 25 = 65 }}}
{{{ 2x = 40 }}}
{{{ x = 20 }}}
{{{ x + 25 = 45 }}}
The hourly rate of the apprentice is $20/hr
The hourly rate of the plumber is $45/hr
