Out with my math and hurry you so much the amount of money in a bank account increased by 21.5% over the last year. if the amount of money at the beginning of the year is represented by n, which expression represents the amount of money in the bank account after the increase? a) n + 0.215n b) n + 21.5n c) 0.215n d) 21.5n

step-by-step explanation:

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.
