Explanation:
We know that Andre started with $100 dollars in his account.
We then see that he made a deposit of $ 70.65. Deposit means to add or put something in.
So we we have to add 70.65 into 100
![100 + 70.65 = 170.65](https://img.qammunity.org/2020/formulas/mathematics/middle-school/2gran8zm4tz7jj5dqwk0j49ezc64wgpob0.png)
Right now, Andre has $170 dollars and 65 cents in his bank account.
We then see that he bought a t-shirt of 19.95
So we then need to subtract Andre's current amount by 19.95
![170.65 - 19.95 = 150.7](https://img.qammunity.org/2020/formulas/mathematics/middle-school/zv2gityh1t2b83crm42jgheuyzrh4ib9q0.png)
He now has $150 dollars and 70 cents in his bank account.
