<h2>
Answer:</h2>
350 dollars
<h2>
Step-by-step explanation:</h2>
<em>(step 1) Find the cost per kilogramme of sugar in shop X</em>
In shop X:
250 grams of sugar costs 150 dollars.
<em>Remember that;</em>
1000 grams = 1 kilogramme.
=> 250 grams will be equal to 0.25 kilogramme
Therefore (replacing 250 grams with 0.25 kilogramme) in shop X;
0.25 kilogramme of sugar costs 150 dollars
Now, if
0.25 kilogramme = 150 dollars,
=> 1 kilogramme = 150 dollars x 1 kilogramme / 0.25 kilogramme
=> 1 kilogramme = 600 dollars
Therefore, the cost per kilogramme of sugar in shop X is 600 dollars
<em>(step 2) Find the cost per kilogramme of sugar in shop Y</em>
In shop Y:
100 grams of sugar costs 95 dollars.
<em>Remember that;</em>
1000 grams = 1 kilogramme.
=> 100 grams will be equal to 0.1 kilogramme
Therefore (replacing 100 grams with 0.1 kilogramme) in shop Y;
0.1 kilogramme of sugar costs 95 dollars
Now, if
0.1 kilogramme = 95 dollars,
=> 1 kilogramme = 95 dollars x 1 kilogramme / 0.1 kilogramme
=> 1 kilogramme = 950 dollars
Therefore, the cost per kilogramme of sugar in shop Y is 950 dollars
<em>(step 3) Find the difference in cost per kilogramme of sugar between the two shops</em>
The difference is calculated by subtracting the cost per kilogramme of sugar in shop X from the cost per kilogramme of sugar in shop Y. i.e
=> cost per kilogramme of sugar in shop Y - cost per kilogramme of sugar in shop X
=> 950 dollars - 600 dollars
=> 350 dollars.
Therefore, the difference in cost per kilogramme is 350 dollars
.
, you can conclude that the imimum value of y will be gained for the minimum value of 
. The minimum value of
