Retta has 40 raffle tickets to sell. she is required to sell at least 15 tickets. she sells the raffle tickets for $10 each. the amount of money gretta makes from selling x raffle tickets is represented by a function. f(x)=10x what is the practical range of the function?

Step-by-step explanation:

Retta has 40 raffle tickets to sell and she has to sell at least 15 tickets. So, the interval that represents this situation is , because the minimum allowed is 15 tickets, and the maximum possible is 40 tickets.

We know by given that the function that models this situation is

To find the valid range, we just need to find the values assigned to and .

Therefore, the practical range of the function is [150,400]

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

the answer would be c:   ax + b = ax + c
