If you triple 4 and subtract 2 each day, how many days until you have zero?
2

D1: 3(4) - 2 = 10
D2: 10 - 2 = 8
D3: 8 - 2 = 6
D4: 6 - 2 = 4
D5: 4 - 2 = 2
D6: 2 - 2 = 0 

So it would be 6 days until you reach zero. Another way you could do it is 12 divided by 2.

Hope I helped :)
 

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
