Explanation / Answer

FV = PV(1+r)n

1. Interest per month = 4/12 = 0.33333%, period I.e. n = 23 years *12 = 276 months

= 3000(1+0.00333333)276

= 3000(1.00333333)276

=3000*2.5054519781

= $7516.3559343

2. AMount deposited = $750-$50 = $700

Interest per quarter = 5/4 = 1.25%

No of period n = 15*4 = 60 quarters

= 700(1+0.0125)60

= 700(1.0125)60

= 700* 2.107181347

= $1475.0269429

7. Interest per month = 9/12 = 0.75%, no of periods n = 20 yes* 12 = 240 months

= 5000(1+0.0075)240

= 5000*6.0091515

= $30045.7576

8.Amount invested= $8000-$720 = $7280

Interest per quarter = 3/4 = 0.75%, no of period n = 5 years * 4 = 20 quarters

= 7280(1+0.0075)20

= 7280 * 1.16118414

= $8453.4205559

9. Interest per half year = 6/2 = 3%, no of period n = 50 years * 2 = 100 half years

= 8000(1+0.03)100

= 8000* 19.218631981

= $153749.05585

10. Interest per month = 8.4/12 = 0.7%, no of period n = 14 years *12 = 168 months

= 20000(1+0.007)168

= 20000 * 3.228130276

= $64562.60552
