Answer:

See missing answers bold

$20 original = $5 final paid           as $15 was s/p before -10 was added

$30 original = $14 final price        as $24 was s/p before -10 was added

$60 original = $35  final price    as $45 was s/p before -10 was added

$92 original  = $69 final price       as $59  was s/p before -10 was added  

Step-by-step explanation:

Ans in bold  

A) = f(x) = 20(0.75) -10 =  15 - 10  = $5                 = £5 final paid

B)= f(x)  30 (0.75) = 24 - 10 = 14                           = $30 original price

C)  = f(x) = 60(0.75) -10 = 45 -10 = $35               = $35 final price

D)     = f(x) = 92 (75) = 69 -10 = $59                    = $92 original price

Complete the following statements in relation to the third term in the expansion of the binomial (2x+y^2)^5
lana [24]
We want to expand (2x + y²)⁵.

From Pascal's Triangle (shown below), the coefficients of the expansion are
1,5,10,10,5,1.

n=0:                        1
n=1:                      1      1
n=2:                   1    2     1
n=3:                 1   3    3     1
n=4:               1   4   6    4     1
n=5:             1   5  10  10   5     1

Therefore the third term in the expansion is 
10*(2x)³*(y²)² = 10*(8x³)*(y⁴) = 80x³y⁴

Alternatively, the third term is
₅C₃ (2x)³(y²)² = 10*(8x³)*(y⁴) = 80x³y⁴

Answer: 80x³y⁴
