The statement is incomplete. The complete description will be shown below:
<em>Solve the quadratic equation </em><em>. Give your answers to 3 significant figures.</em>
From Algebra we know that second order polynomials of the form , can be solved anatically by means of the Quadratic Formula, that is:
(1)
Where , , are coefficients of the given polynomial.
If we know that , and , then the roots of the polynomial are:
That is,
and
$226
1. define the variable x
x = # of days to rent the carpet cleaner
2. substitute x for 7 days
c(7) = 30(7) + 16
3. solve
c(7) = 210 + 16
c(7) = 226
For 7 days, Rhonda will have to rent the carpet cleaner for $226.
