Answer:
$6618 annual payment
Step-by-step explanation:
Employer's annual contribution = $1500 until trust fund distribution
trust fund distribution = $25000
years to trust fund distribution = 20 years
To calculate the amount she must deposit to make up the amount ( future required amount ) she will pay the difference between the required value and the contribution from her employer + trust fund distribution
future value = 1500 FVIFA(8%,30) + 2500 FVIFA( 8%,10)
= 169924( 1500*113.28) + 53973 = 223897
therefore the required total of what she should deposit = 973633 - 223897 = 749735
the amount she must deposit annually is calculated as
749735 ( total payment ) = annuity * FVIFA(8%,30 )
ANNUITY = 749735 / 113.28
= $6618
NOTE : FVIFA (8%,30) and FVIFA( 8%,10) values are gotten from the FVIFA table
