Bean sprouts grow very quickly. A bean sprout has grown to a height of 5 millimetrs. Tomorrow it will be 14 millimeters tall, the next day it will be 23 millimeters tall, and on the next day it will be 32 millimeters tall.

Part 1) Write a rule to represent the height of the bean sprout as an arithmetic sequence.

A(n) = 5 + (n - 1) 9
A(n) = 5 + (n - 1) 9

A(n) = 14 + (n - 1)9
A(n) = 14 + (n - 1)9

A(n) = 5 - (n - 1)9
A(n) = 5 - (n - 1)9

A(n) = 9n
A(n) = 9n

A(n) = 9 + (n + 1)5
A(n) = 9 + (n + 1)5

Answer
A violinist charges $75 for a visit and an additional $25 for each hour she performs.

Part 1) What is the function rule if C represents the total cost of the visit and h represents the number of hours?

(1 point)
Responses

C = 75h + 25
C = 75h + 25

C = 75h - 25
C = 75h - 25

C = 25h - 75
C = 25h - 75

h = 75C - 25
h = 75C - 25

C = 25h + 75
C = 25h + 75

h = 75C + 25
h = 75C + 25
