0 Example: Loan payments of $400 due 95 days ago and $700 due today
guapka [62]

Answer:

X=\$519.48

Step-by-step explanation:

From the question we are told that

Loan 1 X_1=\$400

Loan 1 due t_1=95days

Loan 2 X_2=\$700

Loan 2 duet_2=0days

Payment Y=\$600

Worth of money w=6\%

Payment due t=30days

Focal date t_f=125days

Generally \$400 was due 95days ago

Therefore

125+90=220days(total days to consider)

Therefore

300+400 =700 is due today

125days left

Given

600 due in 30days

125-30=95days

Generally the Final payment is mathematically given by

400(1+ 0.06*\frac{220}{365} ) + 700(1+0.06*\frac{125}{365} )=600(1+0.06*\frac{95}{365} )+X

X=1128.9692 - 609.3698

Therefore the

X=\$519.48
