Play it up game store's daily revenue each can be modeled by r(x) = 50x where x represents the number of games sold each day. the store's daily costs can be modeled by the function c(x) = 8x + 250. find the profit function p(x) if: p(x) = r(x) - c(x)

P(x) = 42x-250.

Step-by-step explanation:

We have just to write P(x), which is R(x) - C(x), so:

P(x) = R(x) - C(x) = (50x)-(8x + 250)

The minus sign before the parenthesis means that everything inside the parentesis must be turned negative, so we have:

P(x) = 50x-8x-250.

Finally, we can add or substract same x-dependant terms, which is, only constants can be added or substracted between them, only terms with x can be added or substracted between them, only terms with can be added or substracted between them, and so on, so we will have:

P(x) = 50x-8x-250=42x-250.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
