Sam borrows $7,500 to buy a car . His loan is for 5 years and charges 6% interest . How much will Sam pay for his car ??

The answer to your question is d 68%

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.

Hold on lemme do the work
