Step-by-step explanation:
Answer:
The amount invested at 4% was $3,000 and the amount invested at 7% was $8,000
Step-by-step explanation:
we know that
The simple interest formula is equal to
![I=P(rt)](https://tex.z-dn.net/?f=I%3DP%28rt%29)
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
![t=1\ year\\ P_1=x\\P_2=11,000-x\\I=\$680\\r_1=4\%=4/100=0.04\\r_2=7\%=7/100=0.07](https://tex.z-dn.net/?f=t%3D1%5C%20year%5C%5C%20P_1%3Dx%5C%5CP_2%3D11%2C000-x%5C%5CI%3D%5C%24680%5C%5Cr_1%3D4%5C%25%3D4%2F100%3D0.04%5C%5Cr_2%3D7%5C%25%3D7%2F100%3D0.07)
substitute in the formula above
![I=P_1(r_1t)+P_2(r_2t)](https://tex.z-dn.net/?f=I%3DP_1%28r_1t%29%2BP_2%28r_2t%29)
solve for x
![680=0.04x+770-0.07x](https://tex.z-dn.net/?f=680%3D0.04x%2B770-0.07x)
![0.07x-0.04x=770-680](https://tex.z-dn.net/?f=0.07x-0.04x%3D770-680)
![0.03x=90](https://tex.z-dn.net/?f=0.03x%3D90)
![x=\$3,000](https://tex.z-dn.net/?f=x%3D%5C%243%2C000)
so
![\$11,000-x=\$11,000-\$3,000=\$8,000](https://tex.z-dn.net/?f=%5C%2411%2C000-x%3D%5C%2411%2C000-%5C%243%2C000%3D%5C%248%2C000)
therefore
The amount invested at 4% was $3,000 and the amount invested at 7% was $8,000
