Bags of flour come in 3 sizes: Small bag: A 200 g bag costs 40p. Medium bag: A 1 kg bag costs £1.80. Large bag: A 2 kg bag costs £3.80. Calculate the cost of 1 kg for the small and large bags. Give your answer in pounds to 2 dp.

Small bag: 1kg cost 200.00p

Large bag: 1kg cost £1.90

Step-by-step explanation:

Small bag: A 200 g bag costs 40p

Medium bag: A 1 kg bag costs £1.80.

Large bag: A 2 kg bag costs £3.80.

Calculate the cost of 1 kg for the small and large bags.

Small bag: A 200 g bag costs 40p

200g cost 40p

1 gram cost 40/200

1 gram = 0.2 p

1000 g = 1kg

1kg cost = 0.2p × 1000

= 200.00p

Small bag: 1kg cost 200.00p

Large bag: A 2 kg bag costs £3.80.

Cost of 1kg = cost of 2kg bag / 2

= £3.80 / 2

= £1.90

Large bag: 1kg cost £1.90

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
