Please help me A hotel has a cost structure represented by the equation C=10x+500, where x is the number of nights. The hotel's revenue is represented by the equation R=45x where x is the number of nights.
A. Use your graphing calculator to find the solution to the system of equations
B. Interpret your solution. How do you know it's correct?

$15 each

step-by-step explanation:

$45/3 children= $15 each

here's a poem i finished a while ago. i hope you like it and that it inspires you.

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
