Sorry to be annoying but there's another question i don't understand... :)

8.20

Step-by-step explanation:

6.15*4=24.6

since they only bought 3 tickets because of the deal

you divide 24.6 by 3 and get 8.20

A ticket costs $8.20.

Step-by-step explanation:

This is because since they only have to buy three tickets, they split the money between each of the four of them. So, we would need to do $6.15 * 4 which equals $24.60, then we divide this number by three to get $8.20 which is the cost of one ticket.

it would be 4 over -2 divided by -1 over 3.

if you want a solution it would be 4

you flip it so it would be 4/-2 divided by 3/-1 then it would be 12/3 and you would simplify it to 4
