Final answer:
Harry has enough money to pay Maria, lend Kelly money for a ticket, and still buy his own movie ticket. After paying Maria and lending Kelly the money, Harry will have $1 left.
Step-by-step explanation:
The question is whether Harry has enough money to pay back Maria $9, lend Kelly $10 for her movie ticket, and still have enough to buy his own movie ticket. Let's calculate:
- Harry has $30 initially.
- He pays Maria $9, which leaves him with $30 - $9 = $21.
- Harry lends Kelly $10 for her ticket, reducing his amount to $21 - $10 = $11.
- A movie ticket costs $10, so Harry can buy his own ticket with the remaining $11 amount.
After these transactions, Harry will be left with $11 - $10 = $1. So, Yes, Harry does have enough money for this situation.
