Option 1
The discriminant of given equation is 116
<em><u>Solution:</u></em>
We have to find the discriminant of given equation
<em><u>Given equation is:</u></em>

To find discriminant,


<em><u>Discriminant is given by:</u></em>

On comparing the given quadratic equation
with general quadratic equation 
a = 4
b = 6
c = -5
<em><u>Substituting in above formula,</u></em>

Thus discriminant of given equation is 116
Since 13,687 vehicles will fit on 14 1,000-space parking lots we have:
14*1,000 = $14,000 will be the cost to lease enough lots to accommodate an overflow of 13,687 vehicles.
