You Need To Create An Equation Then Solve For Their Rates Of Travel.
Answer:
So the portion of the loan lent at 4% is 21000(0.5955) = $12,505.5
And the portion of the loan lent at 15% is 21000(0.4045) = $8494.5
Step-by-step explanation:
This problem can be solved in several ways. The way I like is as follows.
Ask yourself at what interest would $ 21,000 yield and interest of $ 2,215 in one year ? The equation to solve is:
21000(P) = 2215
P = 0.1055 or 10.55 %
This number is a weighed average of the 4% yield and the 15% yield so the next equation to solve is
10.55 = 4(1 – X) + 15X
Where X is the proportion of the loan given at the indicated interest. So
10.55 = 4 – 4X + 15X
6.55 = 11X
X = 0.5955
1-X = 0.4045
So the portion of the loan lent at 4% is 21000(0.5955) = $12,505.5
And the portion of the loan lent at 15% is 21000(0.4045) = $8494.5
Answer:
x=19 and y=28
Step-by-step explanation:
3x-2y=1
-x+y=9 which is x=y-9
Substitute the value of x=y-9 in the equation 3x-2y=1
3(y-9)-2y=1
3y-27-2y=1
y-27=1
y=27+1=28
Substitute the value of y=28 in the equation -x+y=9
-x+28=9
x=28-9=19
Answer:
FYAB gives a better deal.
Step-by-step explanation:
Compound interest:
Continuously compounded interest:
For the quarterly compounded interest, r = 0.25%, and n = 4.
For the continuously compounded interest, r =0.23%
The quarterly compounded doubles in 277 years.
The continuously compounded doubles in 301 years.
Answer: FYAB gives a better deal.
The distance of the point <span>(8, 3.25) </span>to the x-axis (the horizontal line) is 3.25.
incorrect - A.) is 4.75 away from the x-axis
This one is correct - B.) is 3.25 away from the x-axis
incorrect - C.) is 7 away from the x-axis
incorrect - D.) Actually one of the above answers it correct
Hope this helps
