Marta’s starting annual salary is $24,500. At the beginning of each new year, she receives a $2850 raise. Write a recursive formula to find Marta’s salary f(n) after n years. What will Marta’s salary be after 5 years?

A.

f(n) = f(n − 1) − 2850; $38,750

B.

f(n) = 2850f(n − 1); $35,900

C.

f(n) = f(n − 1) + 2850; $35,900

D.

f(n) = −2850f(n − 1); $38,750

f(0) = 24500

f(1) = 24500 + 2850 =  f(0) + 2850 = 27350

f(2) = 27350 + 2850 = f(1) + 2850 = 30200

f(3) = 30200 + 2850 = f(2) + 2850 ...

 

Can you see the pattern now?

I knew what her salaray would be in 5 years I just dont know what the recursive formula would be

Note that, every year she makes $2850 more than the previous one...so.....

 

fn  = f(n -1)  + 2850
