Answer:
times 0.4
Step-by-step explanation:
The recursive formula allows a term in the sequence by multiplying the previous term by the common ratio r
Here
r = =
= 0.4
Thus the recursive formula is
c(n) = c(n - 1) × 0.4 → with c(1) = 500 ← the first term in the sequence
Given:
At the store a cell phone cost 1.1 times as much as it sells online.
The cost of it is $888.98 online.
To find:
How much more does it cost from the store?
