Answer:
5 units were bought
Step-by-step explanation:
Firstly, let us calculate the total amount paid
If what was paid was $9.45, this cost includes the price of the coupon subtracted
Returning the coupon price, we have the total as;
9.45 + 0.5 = $9.95
So to get the number bought, we divide this total by the price for one
We have this as;
9.95/1.99 = 5
Put everything on the same side of the equals sign and set it equal to zero so you can factor it.
. In order to factor that you have no choice really but to put it into the quadratic formula. When you do that you find that your zeros are x = 9.623475383 and -.623475383
Answer:
Step-by-step explanation:
an = a1 * r^(n - 1)
a1 = first term = 5
r = -2
n = nth term of the sequence
so it starts with 5
second term is :
an = a1 * r^(n - 1)......for second term
a2 = 5 * -2^(2 - 1) =
a2 = 5 * -2^1
a2 = 5 * -2
a2 = -10
an = a1 * r^(n - 1)....looking for a3
a3 = 5 * -2^(3 - 1)
a3 = 5 * -2^2
a3 = 5 * 4
a3 = 20
an = a1 * r^(n - 1)....looking for a4
a4 = 5 * -2^(4 - 1)
a4 = 5 * -2^3
a4 = 5 * -8
a4 = - 40
an = a1 * r^(n - 1)...looking for a5
a5 = 5 * -2^(5 - 1)
a5 = 5 * -2^4
a5 = 5 * 16
a5 = 80
an = a1 * r^(n-1)...looking for a6
a6 = 5 * -2^(6 - 1)
a6 = 5 * -2^5
a6 = 5 * -32
a6 = -160
Answer:
1.4 years
Step-by-step explanation:
Use the formula for simple Interest:
Where I is the interest gained (in your case $105),
P is the principal (in your case $6000),
r is the annual interest rate in decimal form (in your case 0.0125)
and t is the time (in years) you need to find.
Therefore, we 
solve for "t" in the following equation:
The mean would jump from $550 to $5550.
The median would jump from $550 to $5275.
