To determine how much change Tyler got back, you need to subtract the cost of the item from the amount he gave the sales clerk:
Change = Amount given - Cost of item
In this case, Tyler gave the sales clerk a 5-dollar bill and the cost of the item was $2.47. So, the change he got back was:
Change = $5.00 - $2.47 = $2.53
Therefore, Tyler got back $2.53 in change.
