To find the account balance after 4 years with simple interest, we can use the following formula:

A = P(1 + rt)

where:

A = the account balance after 4 years
P = the principal amount (initial investment) = $6300
r = the interest rate per year as a decimal = 0.1
t = the number of years = 4

Plugging in these values, we get:

A = 6300(1 + 0.1 x 4)
A = 6300(1.4)
A = 8820

Therefore, the account balance after 4 years with a simple interest rate of 10% would be $8820.
