help solve
You have two numbers. Do you think you should
add?
subtract?
multiply?
divide?
What answer do you get?
I subtracted 40 - 7 = 33 but I feel like there's more to it can you help I'm stuck
Joel -- obviously your answer is wrong. Does she have $33 LESS after 7 weeks of saving???
40x7 = 280 then divided 280 and 7 = 40 so it must be 280 in her account after the 7 weeks?
Now, you've got it! :-) -- almost!
Since we don't know how much was in her account to begin with, we don't know how much is in her account now. However, you're right that it has decreased (gone down) $280 in 7 weeks.
To solve this problem, we need to calculate the total amount of money that Bonita withdraws from her account over the 7-week period.
Since she withdraws $40 every week, we can multiply the amount she withdraws per week ($40) by the number of weeks (7) to find the total amount of money she withdraws.
$40 * 7 = $280
Therefore, Bonita withdraws a total of $280 from her account over the course of 7 weeks.
To find the change in her account balance, we need to consider the direction of the withdrawal. Since she is withdrawing money from her account, her account balance will decrease.
Therefore, the change in her account balance at the end of 7 weeks is -$280.
