djverab [1.8K]

Answer: c(x) = 2.00 + 0.50x

Step-by-step explanation:

Since they already charged her $2.00 leave that alone. They charge her .50 per night, x represents the number of nights she rented the movie. thus the answer is c(x) = 2.00 + 0.50x.

Ms. Coleman's class has already collected 403 cans for a food drive, but the class wants to collect a total of at least 1,000 ca
pochemuha
We need to figure out how many more cans they need to bring.  We figure this out by subtracting 403 from 1,000, which gives us 596 more cans.  We now divide 596/28, to find how many each student would need to bring.  This equals 21.3.  You might want to mention that each student can't bring .3 of a can, so the answer could be 22 also.
