What will be the simple interest earned when you invest $1,000 for 3 years at 10 percent and the compound interest earned when you invest the same sum for 2 years at 5 percent ? the simple interest earned when you invest $1,000 for 3 years at 10 % is $ . the interest compounded when you invest the same sum for 2 years at 5 % is $ .

Investment amount = $1000

Calculate Simple Interest:
Interest for 1 year = 10% x 1000 = $100
Interest for 3 years = $100 x 3 = $300

Calculate compound Interest:
Interest = 1000(1 + 0.1)³ - 1000 = $331

(a) The simple interest earned when you invest $1,000 for 3 years at 10 % is $300.
(b) The interest compounded when you invest the same sum for 2 years at 5 % is $331.

Step-by-step explanation:

Box 1:

180 = 124 + (5x + 11)

56 = 5x + 11

45 = 5x

x = 9

Box 2:

RT = QS

x + 9 = 2x - 5

x = 14

Box 3:

14x - 3 = 18x -19

16 = 4x

x = 4

Box 4:

180 = (9x - 8) + (7x - 4)

180 = 16x - 12

192 = 16x

x = 12

Box 5:

(6x + 34) = (12x - 8)

42 = 6x

x = 7

Box 6:

45 = 7x - 25

70 = 7x

x = 10

Box 7:

54 - x = 3x - 10

64 = 4x

x = 16

Box 8:

12x + 1 = 9x + 16

3x = 15

x = 5

Box 9:

3x + 2x - 5 = 90

5x - 5 = 90

5x = 85

x = 17

Final Code:

(9)(17) = 153
