Question

jina is saving to buy a new gaming system. the function graphed below shows the amount of money, s(x) (in dollars), that jina has left to save after x weeks of saving.
find s(5) and interpret this value.
(a) s(5) =
(b) the answer to part (a) means that after jina has been saving for weeks, she has $ left to save.

Explanation:

Step1: Locate x = 5 on the x - axis (Number of weeks of saving)

Move horizontally from x = 5 until we intersect the graph.

Step2: Read the corresponding y - value (Amount left to save)

From the intersection point, move vertically to the y - axis. The y - value at x = 5 is 160.

Answer:

a) \( S(5)=160 \). This means that after Jina has been saving for 5 weeks, she has \( 160 \) dollars left to save.
b) After saving for 5 weeks, she has \( 160 \) left to save.
