Answer 1

Answer:

9 percent

Step-by-step explanation:

P=10000,S =8.13%

P1=2000,S1=8.00%

P2=4000,S2=7.50%

P3=1400,S3=8.50%

P4=?? ,S4=??

P1+P2+P3+P4=P

2000+4000+1400+P4=10000

P4=2600

P*S=(P1*S1)+(P2*S2)+(P3*S3)+(P4*S4)

10000*8.13=(2000*8.0)+(4000*7.50)+(1400*8.50)+(2600*S4)

Simplify above formula

we will get S4=9.00%
