Answer :
Señior tickets = $10
Student ticket = $9
Step-by-step explanation:
Let :
Senior ticket = x
Student ticket = y
7x + 14y = 196 - - - (1)
5x + 6y = 104 - - - (2)
Multiply (1) by 5 and (2) by 7
35x + 70y = 980 - - - (3)
35x + 42y = 728 - - - (4)
Subtract (3) and (4)
28y = 252
y = 252 / 28
y = 9
From (1)
7x + 14(9) = 196
7x + 126 = 196
7x = 70
x = 10
Hence,
Señior tickets = $10
Student ticket = $9

<u>The rule of 72 </u>
It is a simplified way to determine, If we invest some amount, how long that investment will take to double,
<u>Formula
</u>
Let R be the rate of interest,
The time required to take double the amount = 72/R
