    Step-by-step explanation:

    Cost of 50g of chocolate = 45 p

    cost of 1 g of chocolate = 45/50 p. = 0.9p

    cost of 1kg = 1000g = 0.9 * 1000 p

    = 900 p

    1kg = 1000g

    1000/50 = 20

    So 1kg of chocolate equals 20 lots of 50g chocolate

    One 50g chocolate is 45p

    45p*20=900p

    1kg would cost 900p
