Answer:

$2000

Step-by-step explanation:

The formula for simple interest is:

[tex]i=Prt[/tex]

Where

i is the interest earned

P is the initial deposit

r is the rate of interest (in decimal)

t is the time

Now, in the problem, it is given:

i = 480

r = 4% = 4/100 = 0.04

t = 6

Now, we substitute and find the value of P (initial deposit):

[tex]i=Prt\\480=P(0.04)(6)\\480=P(0.24)\\P=\frac{480}{0.24}\\P=2000[/tex]

Hence, the initial deposit was $2000
