Answer:
I'm assuming that Otto gave the shopkeeper a certain amount of money to pay for the gloves and is expecting some change back. To calculate how much change he will receive, we need to know the amount of money he gave to the shopkeeper.
Assuming Otto gave the shopkeeper 100 kr to pay for the gloves, we can calculate the change he will receive as follows:
Change = Amount paid - Cost of gloves
Change = 100 kr - 76.70 kr
Change = 23.30 kr
Therefore, Otto will receive 23.30 kr back from the shopkeeper. If he gave a different amount of money, you can simply subtract the cost of the gloves from that amount to calculate the change.
