Alan writes the equation A=500(1.25)t to figure out how much it will cost him for a one-year loan of $500 with an interest rate of 25% compounded only once. He wants to determine the annual percentage rate (APR) for a loan that would cost the same amount overall, if it is compounded monthly, instead of only once. Which equation should he use, and what is the APR?

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

roots are from trees

good luck on ur quiz test or homework. have a good day : )
