Answer:

John had $572 in his savings account.

Step-by-step explanation:

Let the total amount John took from his savings account be T.

He spent $52. That means he has $(T - 52) left.

He then spent 1/2 of what was left on presents for his friends. That is:

\frac{1}{2}  * (T - 52) = \frac{T - 52}{2}

Which means he is left with another half of what was left, that is, \frac{T - 52}{2}

Of the money remaining, John put 4/13 into checking account.

This means that he is left with 9/13 of \frac{T - 52}{2}.

We are told that this is equivalent to the last remaining $180 that John left to charity.

=> \frac{9}{13} *  \frac{T - 52}{2} = 108

Hence:

\frac{9(T - 52)}{13 * 2}  = 180\\\\9(T - 52) = 180 * 13 * 2\\\\9(T - 52) = 4680\\\\T - 52 = \frac{4680}{9} = 520\\\\

=> T = 520 + 52 = $572

Hence, John took $572 from his savings account. Since this is all he had in his savings account, John had $572 in his savings account.

You are a member of your local movie theater’s club. Every time you see a movie at the theater, you earn 2 advantage points. Whe
Snowcat [4.5K]

You have to watch 30 movies to earn a free movie pass.

Step-by-step explanation:

Given,

Points earned for each movie = 2 points

Current points = 40 points

Free movie pass = 100 points

Let,

x be the number of movies you have to watch.

2*number of movies + current points = 100

2x+40=100

Subtracting 40 from both sides

2x+40-40=100-40\\2x=60

Dividing both sides by 2

\frac{2x}{2}=\frac{60}{2}\\x=30

You have to watch 30 movies to earn a free movie pass.
