Given that Shanice goes on vacation, and she has $1,750 saved in her checking account for vacation, and each day, she withdraws $125 to pay for meals and entertainment expenses, while Brianna has $550 in her savings account when Shanice goes on vacation, and she deposits $75 from her waitressing job each day into her savings account, to determine on which day will the amount in Brianna's savings account be equal to the amount in Shanice's checking account the following calculation must be made:
- 1750 - (125 x 5) = X
- 1750 - 625 = X
- 1125=X
- 550 + (75 x 5) = X
- 550 + 375 = X
- 925 = X
- 1750 - 750 = 1000
- 550 + 450 = 1000
Therefore, the amount in Brianna's savings account will be equal to the amount in Shanice's checking account on day 6.
