Question

On Monday Jan made withdrawals of 25$, 45$, and 75$ from her saving account. on the same day, her twin sister Julie made withdrawals of 35$, 55$, and 65$ from her saving account.
a- write a sum of negative integers to show Jan's withdrawals on Monday. find the total amount Jan withdrew

Answer 1

We will assume that the total amount is Jan's saving account is "m"

Now, "withdrawal" means that she took money from her account, which means that the amount of money in her account decreased by the amount she withdrew.
Sum of negative integers to show her withdrawals = -25$ - 45$ - 75$
Amount of money remaining in her account = m - 145$
The amount of money Jan withdrew = 25$ + 45$ + 75$ = 145$
