Answer: A
Step-by-step explanation: true true true
The account will be worth $2368.20 in 7 years.
The compound interest formula is

where p is the principal invested, r is the interest rate as a decimal number, n is the number of times the interest is compounded yearly, and t is the amount of time.
3.35% = 3.35/100 = 0.0335.
