WILL MAKE BRAINLIEST IF CORRECT!! A successful author invests some of his earnings in two accounts for 1 year. The function f(x) =.05% models the interest he earns on x dollars invested in the first account. The function g(x) =.075(x + 2500) models the interest he earns from the second account, in which he invests $2500 more than in the first account.
Evaluate (f+g) (18,500) and interpret what it means in this situation.

A) 2500; It means the author earned a total of $2500 from the two accounts
B) 2312.50; It means the author earned a total of $2312.50 from the two accounts
C) 1550; It means the author earned $1550 from the second account
D) 925: It means the author earned $925 from the first account
