Answer :

The cost of 1 kilo of cheese is : 11.6 soles.

Using the parameters given ;

  • Cost of 3/4 of kilo = 8.70

The cost of 1 kilo can be calculated thus ;

3/4 = 0.75 kilo

Now we can find the cost of a kilo using the expression;

0.75 = 8.70

1 = x

take the cross product;

0.75x = 8.70

divide both sides by 0.75

0.75x / 0.75 = 8.70 / 0.75

x = 11.6 soles

Hence, the cost of 1 kilo of cheese is : 11.6 soles.
