Allison:

If John has a toy car collection that is a total of 120 trucks, and John gives away 30 trucks, what is the percent of change in his collection of toy trucks?

Allison:

I did 120/30 which is 4 x.x

Angle:

have you seen this formula before?

Allison:

90/120 = %change/100?

Allison:

Ultrilliam.

Angle:

mmm how much is the "amount of change"?

Allison:

I don’t know.

Angle:

hmmm let me try phrasing is this way: \(percent~change = \large \frac{how ~much~john~gave~away}{how~much~john~started~with}\)

Allison:

Oh 30/120

Angle:

mhm

Allison:

Do I actually divide it

Angle:

yup then turn it into a percent

Allison:

Wut

Allison:

Okay hold.

Allison:

4%

Angle:

hmmm ok, sorry, maybe I went too fast what is 30 / 120 ?

Allison:

0.25

Angle:

then how do you turn a decimal into percent form?

Allison:

..25%...? o.o

Allison:

No? e.e

Angle:

25% is correct :)

Allison:

:D

Allison:

That’s it? O:

Angle:

Allison:

Thank you for helping, you explained well ^-^

Allison:

Do you have time for more if that’s okay?

Angle:

Allison:
