Mr. Warren Buffett invested $20 000. Part of it he put in the bank at 5% interest. Part of it he invested in
netineya [11]

Answer:

Vehicle one he put $10000

Vehicle two he put $1000

Step-by-step explanation:

Interest= PRT/100

Interested= x

P1 +P2= $20000

X1+x2= $1200

R1= 5%

R2= 7%

(P1*5*1)/100= X1

5p1=100 X1.....

P1= 20X1...

(P2*7*1)/100= X2

7p2= 100X2

P2= 100/7 X2

P1 +P2= $20000

20X1 + 100/7 X2= 20000

7X1 +5x2= 7000...equation one

X1+x2= 1200 ....equation two

Multiplying equation two with 7

7X1 +7X2= 8400

7X1 +5x2= 7000

Solving simultaneously

2X2=1400

X2= 700

P2= 100/7 X2

P2= 100/7 (700)

P2= 10000

But X1+x2= $1200

X1= 1200-700

X1= 500

P1= 20X1

P1= 20(500)

P1= 10000

Vehicle one he put $10000

Vehicle two he put $1000
