X = standard and y = high quality

2.4x + 4.8y = 2880
y = 2x

2.4x + 4.8(2x) = 2880
2.4x + 9.6x = 2880
12x = 2880
x = 2880/12
x = 240 <== there were 240 standard version downloads

y = 2x
y = 2(240)
y = 480...there were 480 high quality version downloads

natka813 [3]

There are \frac{30!}{(3!)^{10} } ways for the teacher to decide which student she will teach during each lesson time if she must teach each student exactly 3 times. Here, "!" represents the factorial.

A number's factorial is the result of multiplying the integer by each natural number below it. Factorial can be symbolized by the letter "!". Thus, n factorial is denoted by n! and is the result of the first n natural numbers.

A whole number's "n" factororial is the sum of that number and each whole number up to one.

When a question asks you to determine how many different ways you can arrange or order a given number of items, you use a factorial.
