Question 536286
Let one serving of scrambled eggs = {{{s}}}
Let one double beef whopper = {{{w}}}
given:
{{{ s + w = 300 + 241 }}}
(1) {{{ s + w = 541 }}}
and
(2) {{{ 2s + 3w = 1257 }}}
Multiply both sides of (1) by {{{2}}}, then
subtract (1) from (2)
(2) {{{ 2s + 3w = 1257 }}}
(1) {{{ -2s - 2w = -1082 }}}
{{{ w = 175 }}}
and, since
(1) {{{ s + w = 541 }}}
(1) {{{ s + 175 = 541 }}}
(1) {{{ s = 541 - 175 }}}
(1) {{{ s = 366 }}}
One serving of scrambled eggs has 366 mg cholesterol
One double beef whopper has 175 mg cholesterol
