Step-by-step explanation:
25% × $24 = $6
Subtract the discount from the original
24 - 6 = $18.00
Given:
The function, f(x) = -2x^2 + x + 5
Quadratic equation: 0 = -2x^2 + x +5
where a = -2
b = 1
c = 5
The discriminate b^2 - 4ac = 41
To solve for the zeros of the quadratic function, use this formula:
x = ( -b +-√ (b^2 - 4ac) ) / 2a
x = ( 1 + √41 ) / 4 or 1.85
x = ( 1 - √41 ) / 4 or -1.35
Therefore, the zeros of the quadratic equation are 1.85 and -1.35.

Answer:
£750
Step-by-step explanation:
Total Price = 100 + 20 = 120%
Total Price = £900
120% = £900
1% = 900 ÷ 120 = £7.50
1% = £7.50
100% = 7.5 x 100 = £750
