AI Thread Summary
To determine the cash price of a car purchased on an installment plan, the buyer pays 50,000 upfront and four equal installments of 20,000 each at an 8% effective interest rate. Using the present value of annuity formula, the present value of the four payments is calculated to be approximately 66,243. Adding the upfront payment, the total cash price of the car amounts to 116,243. Additionally, there is a query about the dollar value of the 20,000 installment. The discussion primarily focuses on calculating the total cost of the car based on the given payment structure and interest rate.

Hi everyone. I have a one question about interest rates for my exam, if you help I'd be happy.

A man buys car on instalment basis such that he pays 50.000 on signing of the contract and remaining in 4 equal instalments of 20.000 the first is being paid at the end of first year and so on for each year if the rate of interest is %8 effective, find the cash price of the car?

Formula (present value of annuity):
p = a[1 - 1/(1+i)^n]/i

a = amount of payment (20.000)
i = interest rate (.08)
n = number of payments (4)
p = present value (?)

That will result in p = 66.243,
so price of car = 66.243 + 50.000 = 116.243

Curious: what is value in dollars of 20.000 ?
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
