(1) {{{ c/t = 6/2 }}}
(2) {{{ c + t = 200 }}}
-------------------
(1) {{{ c = (6/2)*t }}}
(1) {{{ c = 3t }}}
---------------
(2) {{{ c + t = 200 }}}
(2) {{{ 3t + t = 200 }}}
(2) {{{ 4t = 200 }}}
(2) {{{ t = 50 }}}
50 pounds of tin are needed
-------------------------
check:
(1) {{{ c = 3t }}}
(1) {{{ c = 3*50 }}}
(1) {{{ c = 150 }}}
------------------
(1) {{{ c/t = 6/2 }}}
(1) {{{ c/t = 3 }}}
(1) {{{ 150/50 = 3 }}}
(1) {{{ 3 = 3 }}}
OK
