First notice that she contributes $300 a month and annually means yearly, so find the amount that she contributes yearly by multiplying 300 by 12 because there are 12 months in a year.
300 * 12 = 3600
Now to find the percentage, divide the amount she contributes in year by her annual salary.
3600/ 72000 = 0.05
Convert 0.05 into a percent by multiplying 0.05 by one hundred.
0.05 * 100 = 5%
A quadratic equation is given by three parameters:
- a is the quadratic coefficient, since it multiplies
- b is the linear coefficient, since it multiplies
- c is the numeric coefficient, since it's a pure number.
The quadratic formula states that the two (possible) solutions for a quadratic equation are
In your case, you have
So, your quadratic equation and its solving formula become
The answer would be either:
-99/10 or -9 9/10
