Mrs. Choi purchased a house for $80000. Five years later, she sold it for a 20% profit and got a 5% broker's commission from the original price. How much did the house sell for?

How much was the profit? ** The 20% profit amounts to $80 000 x 20/100 = $16 000.

How much was the commission? ** The 5% commission amounts to $80 000 x 5/100 = $4 000.

How much did the house sell for? ** So the selling price is $80 000+ $16 000 + $4 000 = $100 000.

Elsa gets 500 MB of cell phone data each month. If she spends 300 MB watching Youtube and 2/5 of what's left on Facebook, how many MB of data does she have left?

How many MB of data does Elsa have left? ** First subtract the 300 MB Elsa spent on YouTube: 500 MB - 300 MB =

<<500-300=200>>200 MB. How many MB of data does Elsa have left? ** Then multiply 200 MB by 2/5th to find out how much data Elsa spent on Facebook: 200 MB * 2/5 = <<200*2/5=80>>80 MB. How many MB of data does Elsa have left? ** Finally, subtract the data Elsa spent on Facebook from the 200 MB: 200 MB - 80 MB = <<200-80=120>>120 MB. #### 120 Lee is saving up for a new pair of sneakers which cost $90.
