GIVING 100 POINTS FOR THIS QUESTION PLS PL SPL SPLS PLS HELPPP!!!!! !!
sergiy2304 [10]

Answer: 65000$ worth of things

This is edited, because I got it backwards last time.

We need to make 2500, but she only makes 4% of whatever she sells.

That means the equation is

2500 = 0.04x

Now, we just need to divide both sides by 0.04 and we get 65000.

Sorry for the confusion.
