Question 1103085
His first rate of investment is:
{{{ ( 35/1500 )*100 = 2.333 }}}
2.333 %
Let {{{ x }}} = amount he should invest
after the raise
{{{ x/1800 = .02333 }}}
{{{ x = .02333*1800 }}}
{{{ x = 42 }}}
He should now invest $42/mo.
-------------------------------
check:
{{{ 42/1800 = .02333 }}}
OK
