Question 737413
Let {{{ q }}} = number of quarters
Let {{{ h }}} = number of half dollars
---------------
(1) {{{ q + h = 27 }}}
(2) {{{ 25q + 50h = 900 }}} ( in cents )
--------------------------------
(2) {{{ q + 2h = 36 }}}
Subtract (1) from (2)
(2) {{{ q + 2h = 36 }}}
(1) {{{ -q - h = -27 }}}
{{{ h = 9 }}}
and
(1) {{{ q + h = 27 }}}
(1) {{{ q = 18 }}}
There are 18 quarters and 9 half dollars
