Answer:
Nominal interest rate is = 9% converible quaterly
we need to find monthy effective interest rate
0.09
i = 0.00744 or 0.75% approximately
i can also be taken as = 0.09/12
now PV of annuity will be the market price i.e x
6 60 *2 ---------------------a
Multiply equation by \frac{1}{1+i} both sides
6 60 2 PV ---------------b
Subtract equation b from a
60 2 PV (1 1+i (1+2)1 (1+2)2 (1+2)3 (1+2)60 (1+961
60 2 PV( 1 +i
on putting i = 0.00744
PV = 2733.88 approximately
X = 2733.88

Answer:
Brand A is the best buy.
Step-by-step explanation:
Brand A has a pack of 28 pencils for 5.29 dollars. This means that the unit cost of one pencil in Brand A would be 5.29/28 = 0.2$ per pencil rounded up to the nearest tenth.Brand B has a pack of 48 pencils for 8.47 dollars. This means that the unit cost of one pencil in Brand B would be 8.47/48 = $0.8 per pencil rounded up to the nearest tenth.Since $0.2 is lesser than $0.8, it means that Brand A is the best buy.
<em>a</em> = 8 - a train arrives at the station once every 8 minutes, so for any given 8 minute interval, a randomly selected train has uniform probability of arriving at the station at some point in this time.
<em>f(x)</em> = 1/8 - the area under the graph of <em>f(x)</em> must be equal to 1. This area corresponds to a rectangle with length <em>a</em> = 8 and height <em>x</em> such that 8<em>x</em> = 1. Solving for <em>x</em> gives 1/8.
<em>P</em> = 5/8 - this is equal to the area under the graph over the interval [0, 5], which is the area of a rectangle with length 5 and height 1/8.
