Question 565775
You have $22 in your bank account and deposit $11.50 each week. 
At the same time, your cousin has $218 but is withdrawing $13 each week. 
When will your accounts have the same balance? How much money will you have after twelve weeks?
Do I use the I=rt formula?
:
No, just a little logic
:
let w = no. of weeks to have the same balance
11.50w + 22 = 218 - 13w
11.50w + 13w = 218 - 22
24.5w = 196
w = {{{196/24.5}}}
w = 8 weeks to be equal
:
:
"How much money will you have after twelve weeks?" You can do this t = total$
t = 11.50(12) + 22
