Substitute teaching calculations
I can only make $1180 a month as a substitute teacher. At location A I make $98 a day, location B $85, and location C $95. What is the least amount of days I could work a month while working at each of the locations at least once? And at what locations?
This is for my mothers work. She had the equation as 95x+98y+85z=1180 but we couldn't figure it out.
