You take
7.25 (10)+5.5p=105.5
72.5+5.5p=105.5
To make the equation easier multiply the whole equation by ten like this
(72.5+5.5p=105.5)10 that equals
725+55p=1055
Then subtract 725 to both sides
725+55p=1055
-725 -725
____ _____
55p=330
Then divide by 55 on both sides and that equals 6 so 6 people bought tickets
They are asking for managers so 996 of them are there, 25% are managers
Change the percent to a decimal (divide the percent number by 100)
You get 0.25
So multiply 996 by 0.25
You get 249
So there are <u>249 managers at the meeting</u>
Y would equal 12 if x were to equal 4. You can think of it as a proportion.

For this case you can solve the problem by applying a simple rule of three in which we have
520 ---> 100%
800 ---> x
Clearing x we have
x = (800/520) * 100 = 154%
the percentage increase in cost was
154-100 = 54%
answer
the percentage increase in cost was 54%
