If the market is offering a 10% discount on all items, the discount on a $45 item is simply 10% of $45. Remember, "10% of 45" translates to:

10/100 * 45

Where "percent" means to divide by 100 and "of" means to multiply. The answer is straightforward from there, just multiply!

(10 * 45)/100 = 4.5

The discount given on the $45 item is $4.50.
