Question 1160617


if a washer {{{w}}} and a dryer {{{d}}} cost ${{{788}}} combined, we have

{{{w+d=788}}}.........solve for {{{w}}}

{{{w=788-d}}}........eq.1


if the washer costs ${{{38}}} more than the dryer, we have

{{{w=d+38}}}.......eq.2

from eq.1 and eq.2 we have

{{{788-d=d+38}}}........solve for {{{d}}}

{{{788-38=d+d}}}

{{{750=2d}}}

{{{750/2=d}}}

{{{d=375}}}



 the cost of the dryer ${{{375}}}
