Question

You have $60.00 in your wallet and want to buy some new CDs. If the CDs are $11.00 each, what number of CDs, x, can you buy? How do you write and solve an inequality?

Answer 1

You can buy 5 CD's

Explanation:

The function would be: `11n<=60`
(usually, the `n`-notation is taken as a whole number)

You then divide both sides by `11`:
`n<=5.4545...`
And since you can't buy part of a CD, the answer is the whole number part.
