D=16n is 16 dollars/ounce
The chart that says 1 under d and 4 under n is 1 dollar/4 ounce
n=4d is 1 dollar/4 ounce
The last chart is 4 dollars / 1 ounce
Answer:
11:50
Step-by-step explanation:
Go back 40 min before 12:20
This is obviously a decreasing sequence. Thus, the common ratio is the fraction 1/4, not the integer 4. Eliminate C and D. Next, at n=1, the value of the 1st term is 16, which is actually 16(1/4)^(1-1) = 16(1) = 16. Thus, B is correct.
