Answer:

price paid of speakers= £40.5

price paid of headphones=£ 5.6

price paid of book=£6.65

price paid of mobile phone=£42

price paid of mouse=£ 15.75

price paid of DVD=£11.05

solution,

1. Cost of speakers:

Discount percent=10 %

Marked price=£45

discount amount= discount % of MP

=10% of 45

=£4.5

Selling price= MP - discount amount

=£45-£4.5

=£ 40.5

2. cost of headphones:

discount amount= discount% of MP

=20% of 7

=£1.4

Selling price= MP- Discount amount

=£7-£1.4

=£ 5.6

3. cost of books:

discount amount= discount percent of MP

= 30% Of 9.50

=£ 2.85

selling price= MP- Discount amount

= £ 9.50-£2.85

=£ 6.65

4. cost of mobile phone:

discount amount= discount% of MP

=40% of 70

=£ 28

selling price= MP- Discount amount

=£70-£28

=£ 42

5. cost of mouse:

discount amount= discount% of MP

= 25% of 21

=£ 5.25

selling price= MP- Discount amount

=£21-£5.25

=£ 15.75

6. cost of DVD:

discount amount= discount % of MP

= 15% of 13

= £ 1.95

selling price= MP- discount amount

=£ 13 -£ 1.95

=£ 11.05

Hope this helps...

Good luck on your assignment..

Aneli [31]
Set up a proportion

75/100= 9 baskets/ x attempts

The ratio of numerator to denominator should be 75/100 which simplifies to 3/4. 3/4= 9/x
3*3=9, 4*3=12

x=12

Final answer: 12 attempts

X+2y=12 <br> 3x-10y = 0<br><br> y=?<br> x=?
sergeinik [125]
~~x+2y=12  \\  ~~3x-10y=0 \\&#10;~------ \\~ -3/x+2y=12 \\  ~~~~~~3x-10y=0 \\ ------- \\ -3x-6y=-36 \\ ~~~~3x-10y=0 \\ +------- \\ ~~~~-16y=-36 \\ \\  ~~~~y= \frac{36}{16}\rightarrow \boxed{\frac{9}{4}} \\  \\
x+2. \frac{9}{4}  =12 \\  \\ x+ \frac{18}{4} =12 \\  \\  \frac{4x+18}{4} =12 \\  \\ 4x+18=48 \\ 4x=30 \\  \\ x=\boxed{\frac{15}{2}}
