[Question]Rebecca runs a hair salon. She charges $30 for haircuts, $40 for perms, and $60 for dye jobs, but she has to buy a box of hair dye for $10 to dye every head of hair. Today, she has four haircuts, one perm, and two dye jobs scheduled. If she makes $50 in tips, how much money will she have in dollars at the end of the day?
[Answer]Rebecca will make 30 * 4 = $120 from haircuts today. She will make 60 * 2 = $120 from dye jobs. She will spend 10 * 2 = $20 on hair dye. With the $40 perm and tips, at the end of the day, Rebecca will have 120 + 120 + 40 - 20 + 50 = $310. The answer is 310.
