Answer:
10 years
Step-by-step explanation:
Let c and s represent the populations of Canyon Falls and Swift Creek, respectively. For time t in years, the respective populations are ...
c = 22500 -740t
s = 15200 +1500t
We want to find t when s = 2c.
s = 2c
15200 +1500t = 2(22500 -740t)
2980t = 29800 . . . . . add 1480-15200, simplify
29800/2980 = t = 10 . . . . divide by the coefficient of t
The population of Swift Creek will be double that of Canyon Falls in 10 years.

Answer: 0.03$ per container or 3 cents per container.
Step-by-step explanation: 2.70/90=0.03.
There's 9 choices for the first digit and 4 choices for the last digit. The number of choices for the 2nd and 3rd digits is 90 if 2 numbers are different. or 100 if duplicates are allowed.
If duplicates are allowed the answer is 9 * 100 * 4 = 3600 possible numbers.
