Solution :
a). Interest for the simple interest
![$= 1000 * 5 * 2$](https://img.qammunity.org/2022/formulas/business/college/8o9fskmsiz94wfok1rpmltk4atcqfbahbs.png)
= $ 100
Amount due for the simple interest = $ 1000 + $ 100
= $ 1100
Amount due for the compound interest
![$= 1000 * (1.05)^2$](https://img.qammunity.org/2022/formulas/business/college/togc29x5tw3p2gstf3j6ozs2c33hm3cfkn.png)
= $ 1102.50
Interest for the compound interest = $ 1102.50 - $ 1000
= $ 102.50
b). Interest for the simple interest
![$= 1500 * 6 * 5$](https://img.qammunity.org/2022/formulas/business/college/bmycrbe0pii1osh7zq4enfzvnwytlykzs5.png)
= $ 450
Amount due for the simple interest = $ 1500 + $ 450
= $ 1950
Amount due for the compound interest
![$= 1500 * (1.06)^5 $](https://img.qammunity.org/2022/formulas/business/college/4tmqs9hzxjjx0tpgonrp2a2o3e1y1cmg23.png)
= $ 2007.34
Interest for the compound interest = $ 2007.34 - $ 1500
= $ 507.34
c). Interest for the simple interest
![$= 1000 * 10 * 10$](https://img.qammunity.org/2022/formulas/business/college/b5eexmimxm8zx73wa9wxxcyw663hx82fsz.png)
= $ 100000
Amount due for the simple interest = $ 10000 + $ 10000
= $ 20000
Amount due for the compound interest
![$= 10000 * (1.10)^(10)$](https://img.qammunity.org/2022/formulas/business/college/11ggl9yhpp9qo4g5g4zvzm0ix99w532j4t.png)
= $ 25937.42
Interest for the compound interest = $ 25937.42 - $ 10000
= $ 15937.42
d). Interest for the simple interest
![$= 25000 * 15 * 15$](https://img.qammunity.org/2022/formulas/business/college/fyyoeb95kvq3n83koqnb89sii36xcoi912.png)
= $ 56,2500
Amount due for the simple interest = $ 25000 + $ 56,250
= $ 81,250
Amount due for the compound interest
![$= 25000 * (1.15)^(15) $](https://img.qammunity.org/2022/formulas/business/college/gip70ecb7fezmsgruzgowa14ptz1n7b2dq.png)
= $ 203,426.54
Interest for the compound interest = $ 203,426.54 - $ 25,000
= $ 178,426.54
e). Interest for the simple interest
![$= 47,750 * 20 * 20$](https://img.qammunity.org/2022/formulas/business/college/x9aubpondmlqkdmy6egmhe4ciug6bt5luy.png)
= $ 191,000
Amount due for the simple interest = $ 47,750 + $ 191,000
= $ 238,750
Amount due for the compound interest
![$= 47,750 * (1.20)^(20) $](https://img.qammunity.org/2022/formulas/business/college/qsloszd3wy9acz47ro1chyh8ebxminpy8o.png)
= $ 1,830,620.40
Interest for the compound interest = $ 1,830,620.40 - $ 47,750
= $ 1,782,870.40
