Answer 2

We have been asked to find the cost of 2Kg of biscuits.

First Let's find the cost of 1Kg biscuit

`\tt\implies \: cost \: of \: 1 \: kg \: biscuit \: = (15)/(2.5) \\ \\ \: \: \tt\implies \: cost \: of \: 1 \: kg \: biscuit \: = 6 \: dollar`

Then Cost of 2Kg biscuit would be

`\tt\implies \: cost \: of \: 1kg \: biscuit \: = 2 * 6 \\ \\ \tt\implies \: cost \: of \: 1kg \: biscuit \: = \: 12 \: dollar`

Hence, the cost of 2 kg biscuit is 12$ .
