Explanation

He spend £140 for 60 jumper

He sells 40%of jumper at £8 for each.

40%of 60

= 40/100 × 60

= 24 jumper

=sells at £8

= 24 ×8 =£192

After ,he sell buy 1 get one half price offer.

Ryan have 60% jumper of 60

= 36/2×8 +36/2×4

=144 + 72

= £216

Total earning= £192 + £216

=£408

So, profit = 408 - 140 = £268

A quadratic equation is shown below:
lys-0071 [83]
16x^2 − 8x + 1 = 0

<span>Part A: 
</span>b^2 - 4ac for ax^2 + bx + c

16x^2 − 8x + 1 = 0
so in this case,
a = 16,  b = -8, c = 1

b^2 - 4ac
=(-8)^2 - (4 * 16* 1)
= 64 - 64
= 0
because it's equal 0, answer is one solution

Part B:

<span>4x^2 − 8x − 45 = 0
</span><span>solve the equation by factoring </span> 
= (2x - 9)(2x + 5)

set (2x - 9)(2x + 5) equal to 0 to solve for x
so
(2x - 9)(2x + 5) = 0
2x - 9 = 0
  x = 9/2
  x = 4.5

2x + 5 = 0
  x = -5/2
  x = -2.5
answer
x = -2.5 or x = 4.5

Hope it helps
