Diana spent $156 on 4 pairs of jeans. If each pair cost the same amount, how much did one pair of jeans cost? Is the answer 39?

answer: 17,082

step-by-step explanation:

you need to multiply the amount of possibilities and then subtract one each time (because one person has been chosen).

the equation is (8*7*6*5)+(9*8*7*6*5)+(9*8)+(7*6*5)

each parenthesis' units correspond to the number of people that can be elected. message me if that doesn't make sense and i can explain it better.
