Ms. Sue · Answer

You have two numbers. Do you think you should add? subtract? multiply? divide? What answer do you get?

Joel · Answer

I subtracted 40 - 7 = 33 but I feel like there's more to it can you help I'm stuck

Ms. Sue · Answer

Joel -- obviously your answer is wrong. Does she have $33 LESS after 7 weeks of saving???

Joel · Answer

40x7 = 280 then divided 280 and 7 = 40 so it must be 280 in her account after the 7 weeks?

Ms. Sue · Answer

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.
