What do you have to do to figure out how much she had before?

legomyego180 · Answer

In other words, if I said hey I just deposited 21.75 to my bank account, now I have $285 dollars but I need to know how much I had before. How would you figure that out?

pannda_lover4 · Answer

by subtracting @legomyego180

legomyego180 · Answer

yea so you could say:
n = the amount you had before

$$n=285-21.75$$

Notice thats not one of your answer choices so you can rewrite this a bit by adding the 21.75 to the other side of the equation like this:

$$n+21.75=285$$

@legomyego180 That is not on of the choices

legomyego180 · Answer

If you care about it: they try to trick you with the first two answers.

You could also rewrite this as:
$$n-285=-21.75$$
