Question

Alex wrote checks on Tuesday for $25 and $50. He also made a deposit in his checking account of $190. Find the overall change in the amount in his checking account.

Answer 1

Answer:

+ $\ 115$

Step-by-step explanation:

When you write a check you are losing money, since it goes out of your account. When you deposit, you add money.

So: $\Delta\ = -\ 25 -\ 50 + \ 190=+\ 115$

Therefore the total change to his account is an increase of $\ 115$.
