  • 1. 
    Mary works part time at a clothing store and makes $240 in a week.  She earns 4% commision on her shirt sales and 6% commission on her jeans sales.  What would be the equation that would represent this situation?  (Let "s" represents the number of shirts she sells and "j" represents the number of jeans she sells)
    • A. 

      4s + 6j = 240
