Step-by-step explanation:

We would apply the formula for determining future value involving deposits at constant intervals. It is expressed as

S = R[{(1 + r)^n – 1)}/r][1 + r]

Where

S represents the future value of the investment.

R represents the regular payments made(could be weekly, monthly)

r = represents interest rate/number of interval payments.

n represents the total number of payments made.

From the information given,

R = \$250

r = 0.06/2 = 0.03

n = 2 × 9= 18

Therefore,

S = 250[{(1 + 0.03)^18 – 1)}/0.03][1 + 0.03]

S = 250[{(1.03)^18 – 1)}/0.03][1.03]

S = 250[{(1.7 – 1)}/0.03][1.03]

S = 250[{(0.7)}/0.03][1.03]

S = 250[23.3][1.03]

S = 250 × 24.03

S = \$6007.5
