Answer:
R = 0.8333%/month
(R = 9.9996%/year)
Equation:
r = (1/t)(A/P - 1)
Calculation:
Solving your equation:
r = (1/4)((8267.7/8001) - 1) = 0.00833333
r = 0.00833333
Converting r decimal to R a percentage
R = 0.00833333 * 100 = 0.8333%/month
Calculating the annual rate
0.8333%/month × 12 months/year = 9.9996%/year.
The interest rate required to get a total amount, principal plus interest, of $8,267.70 from simple interest on a principal of $8,001.00 over 0.333333 years (4 months) is 0.8333% per month.
Answer:
Michelle bought a pack of crayon for $3.25
Step-by-step explanation:
Number of packs = 5
The cost of a pack of crayons =
(Cost of 5 packs of crayon) / (number of packs of crayons)
The cost of a pack of crayons = ($16.25 ) / 5
The cost of a pack of crayons = $3.25
The general form of the quadratic equation is :
The discriminant is :
And the general solution is :
![x=\frac{-b\pm\sqrt[]{D}}{2\cdot a}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-b%5Cpm%5Csqrt%5B%5D%7BD%7D%7D%7B2%5Ccdot%20a%7D)
So, there are 3 situations for D
1. D = 0
So, the roots of a quadratic equation are two similar roots
2. D > 0
so, roots of a quadratic equation are two different roots
3. D < 0
so, roots of a quadratic equation are not real, two comlex roots
The answer would be a 5% discount.
