Answer:
Business-equipment loan, A=$15000
Small-business loan, B=$24000
home-equity loan, C= $39000
Step-by-step explanation:
Let the Business-equipment loan at an interest rate of 11%=A
Let the small-business loan was at an interest rate of 5% =B
Let her home-equity loan was at an interest rate of 4.5%.=C
Since her total Loan=$78000
A+B+C=78000....(I)
Simple Interest = (P X R X T)/100
Since the Time, T=1 year
Interest on A = 0.11A
Interest on B = 0.05B
Interest on C = 0.045C
The total simple interest due on the loans in one year was $4605.
0.11A+0.05B+0.045C=4605....(II)
The annual simple interest on the home-equity loan was $105 more than the interest on the business-equipment loan.
0.045C = 0.11A +105...(III)
We proceed to solve the simultaneous equations.
A+B+C=78000....(I)
0.11A+0.05B+0.045C=4605....(II)
0.045C = 0.11A +105...(III)
From (III), 0.045C = 0.11A +105
Substitute 0.045C = 0.11A +105 into (II).
0.11A+0.05B+0.11A +105=4605
0.22A+0.05B=4500
From (III),
Substitute into (I)
3(31A+9B)=9 X 227000
31A+9B=681000
0.22A+0.05B=4500 (Multiply by 9)
31A+9B=681000 (Multiply by 0.05)
1.98A+0.45B=40500
1.55A+0.45B=34050
Subtracting
0.43A=6450
A=$15000
From (III)
C=$39000
from (I)
A+B+C=78000
15000+B+39000=78000
B=$24000
Answer:
Step-by-step explanation:
The answer you are saying is correct if it was an equation
In inequalities the answer most of the times comes in ranges
The easiest way to find the range is by graphing the equation and finding the values of x for which the graph is above the x axis
There is a good graphing calculator app called desmos if u don't have one
