Carissa and louann both have savings accounts. carissa has $250 in her account and deposits $80 per month. louann has $1230 in her account and withdraws $60 per month.
after how many months will they have equal amounts of money in their accounts? what amount of money will each have when it is the same amount?
it will take months. then, they will both have $
in their accounts.

Carissa value after x months=current+amount deposited
louan value after x months=current-amount taken out

carissa depositied=amount per month times x months=80x
louan take out=amount per month tiems x months=60x

when wil amount be equal
se equal

cariss=lousa
250+80x=1230-60x
add 60x both sides
250+140x=1230
minus 250 both sides
140x=980
divide both sides by 140
x=7

find how much that is
250+80(7)=250+560=810

7 months both have $810
