and can you check my bottom question i answered

Right. His change is $9.31

To calculate the change, we need to subtract the total cost of the telescope from the amount given to the cashier. In this case, Arjun gives the cashier $340, and the telescope costs $330.69. So, the change Arjun will receive is:

Change = Amount given - Total cost
Change = $340 - $330.69
Change = $9.31

Therefore, Arjun will receive $9.31 in change.
