Carol sells tickets for an exhibition. During three days she sold tickets worth $960. One ticket costs $4. How many tickets on average did she sell during one of these three days?
Thoughts? Step-by-step reasoning:
Carol sold 960 / 4 = 240 tickets during three days. So in one day, she sold on average 240 / 3 = 80 tickets.
Thus, the answer is 80.
