Answer:
A. [tex]a_n=128-4n[/tex]
B. 72 ounce remaining
Step-by-step explanation:
A.
Start off is with 128 oz and with each cup (n), 4 oz is gone (subtracted). Thus we can write the sequence as:
[tex]a_n=128-4n[/tex]
B.
To find the amount of water remaining, we have to substitute 14 into n of the formula found above. Thus:
[tex]a_n=128-4n\\a_n=128-4(14)\\a_{14}=128-56\\a_{14}=72[/tex]
Hence, 72 oz is remaining
Answer: 233 oz
