Answer:
$315
Step-by-step explanation:
You are going to want to use the simple interest formula for this. The one below is modified for solving the interest earned.
I = interest amount
P = principal amount
r = interest rate (decimal form)
t = time
Now we can plug in the values into the equation:
This means that Rachel earned $315 worth of interest in the 15 year period.

Answer:
B. $1750
Step-by-step explanation:
The mean of the discrete uniform distribution is given by:
In this problem, we have that .
The expected time to find the car is:
7 hours are expected to find the car.
The helicopter costs $250 per hour to rent.
7*$250 = $1750
So the correct answer is:
B. $1750
Let the weight of the empty jar be J.
Let the weight of a quarter be Q.
J + 125Q = 65 .............(1)
J + 60Q = 52 ...............(2)
Subtracting equation (2) from equation (1), we get:
65Q = 13/65 = 1/5 ounce.
Plugging the weight of a quarter into equation (1), we get:
J + 25 = 65
J = 40
The weight of the empty jar is 40 ounces.
