Question

Jessica has a bubble tea card worth $200. After she bought the first bubble tea, the card’s value is $196.5. After she bought the second bubble tea, its value is $193. After she bought the third bubble tea, the card is worth $189.5. Assuming the pattern continues and that all bubble teas cost the same,

A. A(n) = 200 - 3n
B. A(n) = 200 - 6n
C. A(n) = 200 - 2.5n
D. A(n) = 200 - 4.5n

Answer 1

A. A(n) = 200 - 3n. The correct option for the pattern is A(n) = 200 - 3n.

Step-by-step explanation:

To find the pattern, we can observe that the value of the card decreases by $3.5 each time Jessica buys a bubble tea. So, for every bubble tea she buys (n), the card's value decreases by $3.5. Therefore, the correct option would be A. A(n) = 200 - 3n.
