1. You have some nickels and dimes worth $6.25. You have three times as many nickels as dimes. How many nickels do you have?

2. Mary's age is one third of her dad's age. Seven years ago, her age was one fifth of his. How old are both now?

The next one doesn't seem to make any sense, but here it is...
3. If one machine can sort coins in 15 minutes, and a second machine can sort the same number of coins in 30 minutes, how long would it take both machines working together to do the job?

Please work out the problems instead of just saying the answer. Thanks...

I read of this specimen many years ago, and misplaced the article. The Chimp did not act like other chimpanzees. It would perform complex sequences of assigned tasks involving cleaning up its cell, and then would return to its cot and sit upright on it with its legs crossed -- not manic like other chimps. There was serious speculation that it might be a human/chimp hybrid.

What are some less expensive mathematical software that will just act like a graphing calculator and that will be much cheaper than expensive math programs and how much do the coast ?

I asked one question and am very glad demiurge42 answered it and now I am asking a 2nd question.

while mentioning the roots of a number, we write as + or _ . My question is, should we mention + or _ symbol in the previous step also along with the square root symbol.

The volume of a cylinder is 88 cubic inches. A smaller container, similar in shape, has a scale factor of 1/2. What is the volume of the smaller container? If someone could not only give me the answer, but also explain to me HOW they did the problem, that would be great!

I have many ugly formulas that I have to add 2 to 8 times with a different value of x.
example (x^2)/4 + 456x^3 + (523/17)x^2 + 3x =932.1

I tried entering this:
(x^2)/4 + 456x^3 + (523/17)x^2 + 3x =932.1, x=4
(x^2)/4 + 456x^3 + (523/17)x^2 + 3x =932.1 x=7
(x^2)/4 + 456x^3 + (523/17)x^2 + 3x =932.1 x=9
etc.
etc.
but I get syntax errors

How do I do this with the ti-89 please?
