Just use the calculator to find:

1573(1.02)^10 = 1917.4782226517529659

I just went to WolframAlpha :

H  price =  8 + 2.25 x     where x = number of tickets

P              50 + 1.25 x   

And you wnat to know when they are equal:

8+2.25x = 50 + 1.25 x    Subtract 8 from both sides

2.25x = 42 + 1.25x          Subtract 1.25 x from both sides

x = 42   = number of tickets to equal price  at both carnivals

Add 273.15 to C to get K

3   5    7   11   13  17  19

75 (5 x 5 x 5) = 9375 cm^3

If you have resistances in parallel   r1   r2  r3 and r4   the equivalent resistance is

                1

___________________      =    equivalent resistance

1/r1 + 1/r2 + 1/r3 + 1/r4

- 8b^2 +6b-7  

Pretty heavy soup cans....

5000# is to 3600 cans as x # is to 450 cans

5000# / 3600 cans = x # / 450 cans    Multiply both sides by 450 cans

5000/3600 x 450 = x # = 625 #

This is a very old riddle....ask the guard "what would the OTHER guard tell me is behind this door"   If they answer freedom....take the other door.....if they answer hangman , take that door.
