Answer:
$2,594.34
Step-by-step explanation:
To determine which lease value would make the store owner indifferent between the two options, we have to determine the future value of the first 9 payments that are not paid. Then that value should be equal to the present value of the increase in rent for the next 51 months:
step 1, calculate future value of 9 payments:
F V = payment x [(1 + r)ⁿ - 1] / r
- payment = $2,100
- r = 1%
- n = 9
F V = $2,100 x [(1 + 0.01)⁹ - 1] / 0.01 = $19,674
step 2, calculate the present value of the increase in rent:
PV = payment / {1 - [1 / (1 + r)ⁿ] / r}
- payment = $19,674
- r = 1%
- n = 51
PV = $19,674 / ({1 - [1 / (1 + 0.01)⁵¹]} / 0.01) = $19,674 / 39.8 = $494.34
the new lease payment for which the store owner would be indifferent = $2,100 + $494.34 = $2,594.34
