Question 1058534
Let {{{ p }}} = the price of a popcorn
Let {{{ d }}} = the price of a drink
-----------------------------------
(1) {{{ p + 2d = 18.5 }}}
(2) {{{ p + d = 14 }}}
----------------------------
Subtract (2) from (1)
(1) {{{ p + 2d = 18.5 }}}
(2) {{{ -p - d = - 14 }}}
-----------------------
{{{ d = 4.5 }}}
and
(2) {{{ p + d = 14 }}}
(2) {{{ p + 4.5 = 14 }}}
(2) {{{ p = 9.5 }}}

A large popcorn costs $9.50
A drink costs $4.50
