Sam bought a pair of socks for $2.95 and a tie for $7.50. He have the cashier a twenty dollar bill. How much change should Sam receive from the cashier?

He should receive $9.55 in change.

Step-by-step explanation:

He paid 20 dollars, but he only spent $2.95+$7.50. The amount not needed to pay for the clothes is the change. $2.95+$7.50=10.45, and the amount not needed is $20-$10.45, and that is 9.55. Of course, there might be tax, so this is not exact.
