Answer:
The present value of the contract is 0.5% higher if the rent is paid at the beginning of the month. That is equal to $11.28 for every $100 of rent.
Explanation:
if the rent is paid at the beginning of the month, the present value of the lease contract will be:
PV = monthly rent x PV annuity due factor
we are not given the monthly rent, but we know the PV annuity due factor for 0.5% and 24 periods = 22.67568
if the rent is paid at the end of the month, the PV = monthly rent x PV ordinary annuity factor
the PV ordinary annuity factor, 0.5%, 24 periods = 22.56287
assuming that the rent is $100 (just to calculate a %), the PV of an annuity due = $2,267.57
the PV of an ordinary annuity = $2,256.29
the difference between them = [($2,267.57 / $2,256.29) - 1] x 100 = 0.5%
Direct relation. If iron is used to make steel, and iron is cheaper now, steel will also be cheaper. Decrease in price can mean they have a bunch of it, a surplus.
Supply and demand says if you got a lot of something prices go down. So if you have a lot of cheap iron, you can make a lot of cheap steel
