Question 307064
<font face="Garamond" size="+2">


Let *[tex \Large x] represent the number of hours he worked at this new job, then *[tex \Large 54\ -\ x] is the hours worked at the old job.  He made *[tex \Large 7x] dollars on the new job and *[tex \Large 5(54\ -\ x)] dollars on the old job and 338 altogether, so


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 7x\ +\ 5(54\ -\ x)\ =\ 338]


Just solve for *[tex \Large x]
