in 2006 the cost of fuel was 10% less than the cost in 2005. calculate the cost in cents per litre in 2005

Answer 1

To find the cost in cents per litre in 2005, we'll assume the cost in 2005 is equal to 100 cents.

If the cost of fuel in 2006 was 10% less than the cost in 2005, we can find the cost in 2006 by subtracting 10% from 100 cents.

10% of 100 cents is (10/100)*100 = 10 cents.

So, the cost of fuel in 2006 is 100 cents - 10 cents = 90 cents.

Thus, the cost in cents per litre in 2005 is 100 cents.
