Answer:
15
Step-by-step explanation:
If they started of paying 15 then that's your constant. So what you do is subtract 15 from 45 and see what's left which will be 30. Since each bag of popcorn is $2 you divide the $30 dollars you have left over by 2 and you'll get 15 for the amount of popcorn bags they'll have to buy.

Step-by-step explanation:
Let t be time and r be rate, then if time varies inversely with the rate, the equation is
. If it takes 5 hours to drive a fixed distance at a rate of 80, we can sub those values in to solve for the constant of variation, k.
. Solve for k by multiplying 5 and 80 to get that k = 400. Now let's find a new time t when r is a rate of 70. We will use that k value to do this:
and find that it will take 20 hours to drive the distance at 70 mph when it takes 5 hours to drive the distance at 80 mph. Makes sense that it takes longer to drive a fixed distance when you are going slower.
I believe the answer is 2. i hope this helps
