roblem Solving 3. Does a negative number make sense in this situation? Explain. Victoria withdrew $50 from her checking account.
Answers
Answer:
No. A negative number would not make any sense here.
Step-by-step explanation:
If Victoria withdrew $50, that means, she subtracted 50 dollars from her account money.
If her account money is 5,000; then she withdraws/subtracts $50 from 5,000 which leaves the balance as:
5000 - 50 = $4950.
But, if we try to insert -$50 here, then,
5000 - (-50) = bank balance
(-) + (-) = +
= 5000 + 50 = bank balance
Therefore, bank balance = 5000
To withdraw is already negative in meaning, just like minus and minus become plus, withdraw (negative) and -50 (negative) will become positive, that is to DEPOSIT.

Question :-
- Problem Solving 3. Does a negative number make sense in this situation? Explain. Victoria withdrew $50 from her checking account.
Concept :-
- Let's consider Victoria's bank balance as $10,000. It's clearly mentioned that Victoria withdraws ( it's means subtracting ) $50 from her checking account. Now, it's asked "does a negative number makes sense in this situation?" So, we will solve to see does it mathematically makes sense in this situation or not.
Solution :-
Let's assume $50 as -$50. So,
= $10,000 - ( -$50 )
= $10,000 + $50
= $10,050
Therefore, a negative number doesn't make sense in this situation as withdraws means subtract but here it's added.
