a) Work out the cost of 100g of each type of tea
b) Which type of tea is the cheapest?

The cheapest is the Kenyan tea which costs  £1.05  for each 100g.

Step-by-step explanation:

A)

200 g of Kenyan tea costs £2.10

1. Calculate the rate of each gram, by dividing 2.10/200

0.0105 x 100 =    £1.05  for each 100g

300 g of Columbian tea costs £3.45

1. Calculate the rate of each gram, by dividing 3.45/300

0.0115 x 100 =  £1.15 for each 100g

1. Calculate the rate of each gram, by dividing 1.70/150

150 g of Indian tea costs £1.70

0.01133333333 x 100 =  £1.133333333 for each 100g

B) The cheapest is the Kenyan tea which costs  £1.05  for each 100g.
