Question 1053604
{{{ x }}} = the number of quarters
{{{ 4x }}} = the number of nickels
--------------------------------
{{{ 4x + 7 }}} = the number of dimes
( I think. The wording is vague to me. )
------------------
{{{ 25x + 5*(4x) + 10*( 4x + 7 ) = 240 }}} ( in cents )
{{{ 25x + 20x + 40x + 70 = 240 }}}
{{{ 85x = 170 }}}
{{{ x = 2 }}}
and
{{{ 4x = 8 }}}
and
{{{ 4x + 7 = 4*2 + 7 }}}
{{{ 4x + 7 = 15 }}}
---------------------
There are 2 quarters, 8 nickels, and 15 dimes
I guess I got it.
