Algebra 1

Ok, these questions were one's that I couldn't figure out how to work. If someone could set me up on how to solve each one it would be great. Thank you!

1. A movie theater had a certain number of tickets to give away. Five people got the tickets. The first got one-third of the tickets, the second got one-fourth of the tickets, and the third got one-fifth of the tickets. The fourth person got eight tickets, and there were five tickets left for the fifth person. Find the total number of tickets given away.


b. About 35.9% of all charitable contributions are made to religious organizations. In 2003, about $86.4 billion was given to religious organizations. How much was given to charities in general?



3. It costs $225 per month plus 1.2¢ per copy to rent a copy machine. A catalog publisher needs to lease a copy machine for use during a special project that they anticipate will take 3 months. They decide to rent the copier, but must stay within a budget of $2400 for copies. Determine (in terms of an inequality) the number of copies they can make and still remain within budget.


( for this one, I think I did it right, and would love for someone to check it for me. If it's wrong, could you tell me what my mistake was?)


4. Simplify. Describe the steps you used to arrive at your final answer.

2(to the 3rd power) - 10[4-(-2+18)3]

I got : 432


TY again.

  1. 1. Let x = total number

    x - 1/3x -1/4x - 1/5x - 8 = 5

    Solve for x.

    b(?). 86.4 = .359x (in billions)

    3. 3(225) + .012x < 2400, where x = number of copies.

    4. x^2 = x squared online. What are you doing with the final 3 in the formula? What is missing?
