URGENT!! I NEED HELP ASAP NOT ROCKY

Anestetic [448]

Answer:

$9000

Step-by-step explanation:

Given

Monthly payment P = $300
Time t = 3 years = 36 months
Number of payments n = 36
Interest rate r = 12% PA = 1% per month = 0.01 times

Use loan payment formula:

P = r(PV) / (1 - (1 + r)⁻ⁿ),
where P- monthly payment, PV - present value (amount of the loan), r -rate of interest, n- number of payments

Substitute values and solve for PV:

300 = (0.01*PV) / (1 - (1 + 0.01)⁻³⁶)
PV = 300*(1 - 1.01⁻³⁶ )/ 0.01
PV = 9032.25 ≈ $9000 (rounded to the nearest hundred dollars)

$1,620 is shared between Samantha and Catherine. Catherine’s share is $60 more than Samantha's share

lyudmila [28]

1620-60=1560 to share between them (since Catherine has 60 more). 1560/2=$780
