Question

you own a pet store that sells fish tank you brought a fish tank for $35 and are going to mark it up 20% what is the selling price going to be on the fish tank

Answer 1

If you're marking the fish tank up by 20%, it means you're looking to sell it at 120% of its original value.

Now, let's use a rule of three to calculate such percentage:

Thereby,

`x=(120\cdot35)/(100)\rightarrow x=42`

The selling price would be $42
