Question 278526
<font face="Garamond" size="+2">


If each load costs $1.25, then the total you will spend for *[tex \Large x] loads of laundry is *[tex \Large 1.25x].  If you can do 4 loads for $1.00 at home, then each load costs about $0.25, and the cost for *[tex \Large x] loads is *[tex \Large 0.25x].  You need to know the value of *[tex \Large x] so that *[tex \Large 1.25x] is equal to *[tex \Large 0.25x] plus the $400 that the washer costs:


Solve:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 1.25x\ =\ 0.25x\ +\ 400]


for *[tex \Large x]
