Answer: A
Step-by-step explanation:
I think it is A because p*(10-2). Can = (p*10)-(p*2)

The problem is that 7^2 is 7*7, and the same for 8^2. The right answer is the square root of 15, or 3.87
The future amount of the current deposit given that the interest is simple and yearly is computed through the equation,
F = P x (1 + in)
where P is the principal amount, F is the future amount, i is the interest (in decimal form) and n is the number of years.
In this certain problem, we substitute the known values to the equation and solve for P,
2419.60 = P x (1 + (0.052)(1))
P = 2300
Thus, the initial investment was worth $2,300.
