Total investment = $10,500
Let x = amount of first investment, and y the amount of the second investment.
First investment:
Interest rate = 9 (1/5)% = 0.092
Earned interest = 0.092x
Second investment:
Interest rate = 9% = 0.09
Earned interest = 0.09y
Total interest after one year is $957.00, therefore
0.092x + 0.09y = 957
or
1.0222x + y = 10633.33 (1)
Also,
x + y = 10500 (2)
Subtract (2) from (1).
0.0222x = 133.33
x = 6000
y = 10500 - x = 4500
Answer:
The first investment is $6,000 at 9 (1/5)% rate;
The second investment is $4,500 at 9% rate.
Answer:
x = 3.5
Step-by-step explanation:
f(x) = 2x + 3
g(x) = 24 – x
-> g(14) = 24 - 14
-> g(14) = 10
f(x) = g(14) (Given)
-> 2x + 3 = 10
-> 2x = 10 - 3
-> 2x = 7
-> x = 7/2
-> x = 3.5
Answer:
1 3/5 = 8
2 = 10
Step-by-step explanation:
1 3/5 is 1.60 in decimal form so divide 1.6/0.2
2 is 2 so divide that by 0.2
Answer:
C
Step-by-step explanation:
f(5) means we must plug in 5 wherever we see an x in the function.
<u>So f(5) = 27! The answer is C.</u>
