Answer:
See below, please!
Step-by-step explanation:
We can set up a system of equations to model this problem. Let's consider the student's ticket as x, and y for the adult ticket.
So since the student ticket is $1.50, and adult is $4, we can set up the following equation: 
, since they collected $5050 total.
We can set up another equation modeling the number of people who came to the game. This would be x+y=2200.
Solve this, and we get x= 1500 and y=700. So, they sold 1500 student tickets and 700 adult tickets.
Hope this helped!

Answer:
a) non-proportional/ constant rate: 3
b) non-proportional/ constant rate 3
Step-by-step explanation:
I think the logical question for this would be to find the reaction rate constant, k, for radioactive decay of Rhodium. The general formula is:
ln A/A₀ = -kt,
where
A is the amount of substance after time t,
A₀ is the original amount of substance
t is the time
After 30 s, the amount of Rhodium would be in half. So, A/A₀ = 1/2
ln(1/2) = -k(30 s)
k = 0.023 s⁻¹
