Danh has positive 220 dollars in his bank.He Withdraws negative 50 dollars every day for one week straight.
How much money will Danh have after one week?
Total amount of money he withdraw in a week: 50x7= $350
This is the amount AFTER he withdraw money: 220-350=$-130
Steps to solve: You first have to find how much he had owed altogether which was 350.Then you had to subtract 250 by 350, but first you had to change the subtraction sign to a addition sign. After that you had to change positive 350 to negative 350. Then you add the numbers together and you will have -130 because the bigger number gets the sign when there are two different number signs.
