An ice cream store charges 75 cents for each scoop of ice cream and 25 cents for each cone. how many scoops would be in one ice cream cone if it cost a total of $4?

0.25 +0.75x = 4
0.75x = 4 - 0.25
0.75x = 3.75
x =3.75/0.75
x = 5

In one ice cream cost $4, there will be 5 scoops .

double check:

5(0.75) = 3.75 (amount pay for scoops)
            + 0.25 (one cone)
 
                $4.00 total cost

Do you need with the x value for the minimum? its always between the two intercepts for a parabola
