Answer:

Case 1: a = 1.5, b = 2, c = -3

$D = 22$

Case 2: a = 2.3, b = -4, c = 1

$D = 6.8$

Case 3: a = 3.7, b = 9, c = -4

$D = 140.2$

Case 4: a = 4.6, b = -8, c = 5

$D = -28$

Case 5: a = 5.5, b = 7, c = -3

$D = 115$

Case 6: a = 6.9, b = -5, c = 2

$D = -30.2$

Case 7: a = 7.2, b = 6, c = -4

$D = 151.2$

Case 8: a = 8.3, b = -3, c = 4

$D = -123.8$

Case 9: a = 9.9, b = 4, c = -7

$D = 293.2$

Case 10: a = 10.4, b = 8, c = -5

$D = 272$

Step-by-step explanation:

For all second order polynomial, the discriminant is equal to:

$D = b^{2}-4\cdot a \cdot c$

Case 1: a = 1.5, b = 2, c = -3

$D = 22$

Case 2: a = 2.3, b = -4, c = 1

$D = 6.8$

Case 3: a = 3.7, b = 9, c = -4

$D = 140.2$

Case 4: a = 4.6, b = -8, c = 5

$D = -28$

Case 5: a = 5.5, b = 7, c = -3

$D = 115$

Case 6: a = 6.9, b = -5, c = 2

$D = -30.2$

Case 7: a = 7.2, b = 6, c = -4

$D = 151.2$

Case 8: a = 8.3, b = -3, c = 4

$D = -123.8$

Case 9: a = 9.9, b = 4, c = -7

$D = 293.2$

Case 10: a = 10.4, b = 8, c = -5

$D = 272$

30% of 120

= 0.3*120

= 36

120 - 36 = 84 (discounted adult ticket)

60% of 120

= 0.6*120

= 72

120 - 72 = 48 (discounted childrens ticket)

84*2 = 168

48*3 = 144

168 + 144 = 312
