Shawn has a balance of $1200 on a credit card with an apr of 18.7%, compounded monthly. about how much will he save in interest over the course of a year if he transfers his balance to a credit card with an apr of 12.5%, compounded monthly?

Answer is D = 121.51

Use the Compound Interest Formula

A = P (1 + (R/12)/100)^(12*n)

Run 2 case

P = 1700

R = 18.7, R = 12.5

n = 1 (as the problem is asking over the course of a year)

Solve for A for both the R and subtract the two values of A to obtain ~121.51

Step-by-step explanation:

it has the same slope and a different y-intercept

hope this : )
