Solving Problems with Integers

100

if my account balance after transaction 1 was $250 and my balance after transaction 2 was $145, did I withdraw or deposit money in my account? (How do you know?)

withdraw

200

If my account balance after transaction 1 was $250 and my account balance after transaction 2 was $145, what was the amount of my transaction 2?

- $105

300

If my account balance after transaction 1 was $250 and my account balance after transaction 2 was $-20, what was the amount of my transaction 2?

  -$270

400

My account balance after transaction 1 was $250 and my account balance after transaction 2 was $145. Using x to represent the amount of money you withdraw, write an equation to represent the situation in relation to my account.

250 + x=145   or -145 -250 =x

500

My account balance after transaction 1 was $320 and my account balance after transaction 2 was $-100. Using x to represent the amount of money you withdraw, write an equation to represent the situation in relation to my account.

320 + x = -100
