Emaan charges a fixed amount for a bracelet, with an additional charge for each charm a customer adds to the bracelet. Write a linear function "f" that Emaan can use to find the price of a bracelet. Charms: 5,10,20,30
Cost ($): 110, 180, 320, 460

A. f(x) = 2x + 100
B. f(x) = 14x + 40
C. f(x) = 6x + 80
D. f(x) = 12x + 60

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
