Answer 2

27,200

Explanation:

P = 20,000

r = r%

n = 2 years

A = 24,000

• A= Prt/100 + P
• A= (20,000*r*2)/100 + 20,000
• 24,000 =40,000*r +20,000
• 24,000 - 20,000 = 40,000*r
• 4,000 = 40,000*r
• r= 10%

If r = (r+2)%

  r = (10+2)%

  r = (12)%

and n=3 years

• A= Prt/100 + P

• A= 20,000*12*3/100 +20,000
• A=7,200+20,000
• A= 27,200
