Question 132197
{{{j}}}= cost of a case of juice
{{{w}}} = cost of a case of water
(1) {{{135 = 6j + 1w}}}
(2) {{{110 = 4j + 2w}}}
Divide (2) by {{{-2}}} and add to (1)
{{{135 = 6j + 1w}}}
{{{-55 = -2j - 1w}}}
{{{80 = 4j}}}
{{{j = 20}}}
(1) {{{135 = 6j + 1w}}}
{{{135 = 6*20 + w}}}
{{{w = 135 - 120}}}
{{{w = 15}}}
The juice costs $20 per case and the water costs $15 per case
