The discriminant is the term under the radical sign in the quadratic formula.

x=(-b+-(b^2-4ac)^(1/2))/(2a)

It is the b^2-4ac part.  (a,b,c from the standard quadratic of form ax^2+bx+c)

In this case:

10^2-4*3*4

100-48

Given:

Number of bottles of pop purchased = 4

Number of candy bars purchased =  3

Number of chips bag  purchased = 2

Cost of per bottle of pop = $1.25

Solution:

Let the cost of one chips bag be x

Cost of  4 bottles of pop

=>4 \times 1.25

=>$ 5

Cost of 3 candy bars

=>3 \times 0.90

=>$ 2.7

Cost of 2 bags of chips

=>2 \times x

=>$ 2x

Now the total cost of the bill is

T = 5 + 2.7+ 2x

T =7.7+2x

Also Krystal had a coupon worth $1.50, the cost of the ticket will be

T =(7.7+2x) - 1.50
