I think that it could be C. 13/12
Answer: 5894.2
Step-by-step explanation:
You'll want to follow PEMDAS to simplify this expression.
1.) P - Parentheses
2.) E - Exponents
3.) M - Multiplication
4.) D - Division
5.) A - Addition
6.) S - Subtraction
We'll start with what's inside the parentheses:
(2.4 × 1018) + (3.4 × 1015)
(2,443.2) + (3,451)
Now all you have to do is add the values together to get your answer!
2,443.2 + 3,451
5894.2
Missing the total payment information. Can not solve without total cost...
Answer: he invested $46062.5 at 6% and $23031.25 at 10%
Step-by-step explanation:
Let x represent the amount which he invested in the account paying 6% interest.
Let y represent the amount which he invested in the account paying 10% interest.
He puts twice as much in the lower-yielding account because it is less risky.. This means that
x = 2y
The formula for determining simple interest is expressed as
I = PRT/100
Considering the account paying 6% interest,
P = $x
T = 1 year
R = 6℅
I = (x × 6 × 1)/100 = 0.06x
Considering the account paying 10% interest,
P = $y
T = 1 year
R = 10℅
I = (y × 10 × 1)/100 = 0.1y
His annual interest is $7370dollars. it means that
0.06x + 0.2y = 7370 - - - - - - - - - -1
Substituting x = 2y into equation 1, it becomes
0.06 × 2y + 0.2y = 7370
0.12y + 0.2y = 7370
0.32y = 7370
y = 7370/0.32
y = $23031.25
x = 2 × 23031.25
x = 46062.5
