A rational number is any number that can be wrote as a fraction (p/q). A rational number is the quotient or fraction of two integers. It is seen as a ratio of two integers as well. Repeating/terminating decimals are also rational numbers as they can be shown as the ratio of two integers. (p/q) the fraction, will have both the numerator and denominator being whole numbers.
what we can do: Look at each number in the sequences and see which will have only rational numbers. A: 0 is rational, 1/2 is rational because it is a ratio of two integers, 1.5 is rational because it can be written as 3/2, and 2.82843 is rational because it can be wrote over one as a ratio of two integers.
So A is the only list that contains only rational numbers.
Profit is total revenue minus total cost. So, the profit for each row of data is: Quantity | Profit 0 | 30 (loss) 1 | 30 2 | 160 3 | 190 4 | 260 5 | 300 6 | 310 7 | 290
The company has to produce 6 quantities to maximize profit.
