Answer:
adult $13 student $15
Step-by-step explanation:
A=adult S = student
9A + 4S = 177
1A + 4S = 73
Multiply the second by (-1)
9A +4S = 177
-1A -4S = -73
ADD BOTH (4S will be cancelled)
8A = 104
A = 13 ( Adult ticket = $13)
13 + 4S = 73
4S = 60
S = 15 ( student ticket $15)

Answer: The balance in the account increases at a rate of 2.5%
Step-by-step explanation:
The balance in the account after x years is modeled by
b (x) = 850(1.025)x
In another form
b(x) = 850(1 + 25%)^x
Where
850 = initial deposit
25% = Interest rate
"+" sign signifies the increase
Therefore the balance in the account increases at a rate of 2.5%
