katrin2010 [14]

Answer:

Initial amount P = $12000

Interest after 2 years I = 4%*2 = 8%

<u>Investment into Trust fund:</u>

  • $12000 + $5000 + 0.08*$12000 = $17960

<u>Interest amount to exceed $20000:</u>

  • $20000 - $17960 = $2040

<u>Time required to get $2040:</u>

  • 17960*0.045x = 2040
  • 808.2x = 2040
  • x = 2040/808.2
  • x = 2.52 years

The investment will exceed $20000 in the second half of the third year

Solution given:

x. \:\:\: f. \:\:\: fx

13. \:\:\: 15. \:\:\: 195

14.\:\:\: 42 \:\:\: 588

15. \:\:\: x. \:\:\: 15x

16. \:\:\: 10. \:\:\: 160

17. \:\:\: 3. \:\:\: 51

. n=70+x. \sum=994+15x

we have

mean=sum/n

14.44=\bold{\frac{\sum}{n}}

14.44=\bold{\frac{994+15x}{70+x}}

doing crisscrossed multiplication

(70+x)*14.44=994+15x

1010.8+14.44x=994+15x

15x-14.44x=1010.8-994

0.56x=16.8

x=16.8/0.56

x=30
