Answer:
If it costs 5% of $75 it would be $3.75
If it is 5% off $75 it would be $71.25
How we find the answer.
To find 10% of an item you move the decimal point once to the right
If we do this to 75.00 it would be 7.500
We can remove the two 0's
7.5
We are not looking for 10% though we are looking for 5%
Half of 10 = 5 so half 7.5
3.75 is 5% of 75
---------------------------------------
Now if we want to find out 5% off of 75 we subtract
75.00 - 3.75
71.25
