Luke had 2 ten dollar bills. his younger sister leia had a five dollar bill. they combined their money to buy a gift for their father that costs $22. how much change did they received

They received 3 dollars in change. Luke has 2 ten dollar bills (2*10), so he has $20. Leia has a five dollar bill ($5). If you add $20 and $5, you get $25. If the gift costs $22, then subtract $22 from $25 (how much money Luke and Leia have combined). $25 - $23 = $3

The answer is 3 one dollar bills
