Answer:
Refer to the first number line. You would start counting five units to the right from -6. You would stop at -1 and that is the answer to the question
Problem 2:
Anna had $4 balance in her bank account. She used her debit card to purchase a meal deal that costs $5. Her bank account allows overdraft. What amount would her bank statement shows if Anna had not deposit any money since her last purchase?
Answer: Over draft means that a bank allows their customer to make purchase more than what they've got left in their balance but this means the customer will be in debt to the bank. Anna had $4 in the bank and she made a purchase of $5. Her bank statement would show
4 - 5 = -1
Using the number line, you would start from 4 and count back 5 to get to -1

Answer:
Yes; she will have $4008 for other expenses.
Step-by-step explanation:
First you find out how much she saved by multiplying 350 by 36 as she saved for 3 years which is 36 months.
After that you need to work out the amount she needs in total for her tuition by multiplying 4 by 3723 which is the amount needed per year.
If her parents add to her account half the amount she saved that means that they give her an additional 6300 as that's half of 12600.
This means she has 18900 and if you take away 14892 you will be left with 4008 for expenses.
