Mr. Phan fills a portion of his pool with water on
Monday. Then on
Tuesday, he fills the pool
with water coming from a
hose at a constant rate.
The table shows the
number of feet of water
in the pool as a function
of time on Tuesday.
What is the rate of
change of the function?

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

the bolded word " farsighted" could be replaced with visionary.

my best guesses would have to be either 4.5 or 2. p.s. if they're wrong, i'm so sorry for giving you the wrong answer.
