The answer is A, because 7.5 times 400 is 3000 so you need at least 400 boxes.
Answer:
I'm pretty sure 10.
Step-by-step explanation:
Answer: The 1st option is the answer.
Step-by-step explanation:
So let your explicit rule be f(x) = 14 - 9x.
The gradient of this graph is the coefficient of x, which is -9. So each time x is increased by 1, f(x) increases by -9, which is to say it decreases by 9.
So a(n) = a(n-1) -9.
And a(1) = 14 - 9 × 1, which is 5. We get this by substituting i for n.
So your answer is the 1st option.
