Let {{{ a }}} = pounds of large shrimp
Let {{{ b }}} = pounds of popcorn shrimp
-------------------------------------------
(1) {{{  5a + 1*b = 30 }}}
(2) {{{ a + b = 10 }}}
-----------------------------------
Subtract (2)from (1)
(1) {{{ 5a + b = 30 }}}
(2) {{{ -a - b = -10 }}}
------------------------
{{{ 4a = 29 }}}
{{{ a = 7.25 }}}
and
(2) {{{ 7.25 + b = 10 }}}
(2) {{{ b = 2.75 }}}
