Please hell will medal!
You have $22 in your bank account and deposit $11.50 each week. At the same time your cousin has $218 but is withdrawing $13 each week. When will your accounts have the same balance?
ok so x will be the number of weeks it will take to get the same money. First, make the equation 22+11.50w=218-13w this equation says that you have $22 and you will gain $11.50 each week. This will be equal to the amount of how your cousin in a certain number of weeks. He has $218 and loses $13 a week. 22+11.50w=218-13w -22 from both sides 11.50w=196-13w then add 13 w to both sides 24.50w=196 now divide both sides by 24.50 so the "w" is alone. you will end up with: w=8 so you know that in 8 weeks you and your cousin will have the same amount of money And after 12 weeks, you just use the starting equation: 22+11.50w=218-13w and add in the value of 12 to both w's 22+11.50(12)=218-13(12) 22+138=218-156 160=62 the left is the amount you will have and the right is the amount your cousin will have. After 12 weeks you have: $160 cousin: $62
