The expression below represents the cost, c, of an item that is on sale for 25% off.

C-0.25c

Which expression is also equivalent to the cost of the item?

0.75c

1 - 0.750

1 - 0.25c

0.25c

Another way of solving for the price when the item is on sale for 25% off is to subtract the rate from 100% and multiply it by C.

So for this problem, 100% - 25% = 75%.

The equivalent equation will be 0.75c

The equivalent of the cost of the item is 0.75c
