Step-by-step explanation:
<u>Simple Interest</u>
Definition: Interest calculated on the original principal only of a loan or on the balance of an account.
Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.
The interest earned is calculated as follows:
I=P.r.t
Where:
I = Interest
P = initial principal balance
r = interest rate
t = time
Marving is saving money in a savings account with a simple interest rate of r=7.5%=0.075. It's known that after t=12 years, the account had earned $288 interest. Substituting in the formula:
288 = P*0.075*12
Calculating:
288 = 0.9P
Dividing by 0.9:
P = $320
Correct choice: C. $320
Answer:1 quarter, 2 dimes and 1 nickel, 5 nickels, 3 nickels and 1 dime
Step-by-step explanation:
Answer: the answer is 2x-3=15
Step-by-step explanation: It’s simple so whenever you see x in the equation you just plug 9 in it’s place for example:
equation 1: 2x-3=15 —> 2(9)=18-3= 15 for this equation 9 is the solution
equation 2: 4+5(9)=18 —> 4+45=49 and 49 does NOT equal to 18 therefor 9 is not a solution
equation 3: 3(9)+2= 29 and 29 does NOT equal to 25 so 9 is not the solution
equation 4: 81(9)-3=6 —> 726 does NOT equal to 6 so not a solution
equation 5: 24-2(9)=13–> 6 does not equal to 13 so 9 is not a solution
equation 6: 3(9)+7=8 —> 34 does not equal to 8 so 9 is not a solution
(hope this helps)
Answer:
A
Step-by-step explanation:
it isn't a straight line, so it is nonlinear
Try this: 0.75n = 15. Divide both sides by 0.75 to solve for n: n = 15/0.75
n = 20
There are originally 20 oranges.
