Question 777927
Let {{{ n }}} = the number of dimes, nickels, and pennies
{{{1*n + 5*n + 10*n = 1344 }}} ( in cents )
{{{ 16n = 1344 }}}
{{{ n = 84 }}}
There are 84 of each type of coin
check:
{{{ 1*n + 5*n + 10*n = 1344 }}} 
{{{ 1*84 + 5*84 + 10*84 = 1344 }}} 
{{{ 84 + 420 + 840 = 1344 }}}
{{{ 1344 = 1344 }}}
OK
