Explanation:

Answer 2

we have to pay $ 1.0712.

Explanation:

Given:

Cost of cheese per kilo gram= $ 53.56

To find:

Cost of 20 grams of Cheese=?

Solution:

Now, we know that,

1 kilo gram = $ 53.56

Then,
`20 grams = 20*(1)/(1000) kilo grams` .......... ( let it be ) $ n

So, by cross multiplication method,

=>
`n * 1 = 53.56 * 20* (1)/(1000)`

=>
`n = 53.56 *( 1)/(50)`

=>
`n = (53.56)/(50)`

=>n = 1.0712
