## anonymous 5 years ago problem i need help suppose the probability of rain is 50%. what profit can the concession stand expect to make? this are the equations (p=2.50v-500 and v=600-500r)

hey

could you give the exact question as written?

thats the exact question thats why i don't ge it

Suppose r = P(rain), p = profit and -600 and -500 are constant expenses: Now: $P(rain) = 0.5$ Thus: $p=2.5*(600-500*0.5)-500=375$ We can also find out that when: $\lim_{r \rightarrow 1} 2.5*(600 - 500*r) - 500$ $p \rightarrow-250$ and $\lim_{r \rightarrow 0} 2.5*(600 - 500*r) - 500$ $p \rightarrow1000$
