Melanie has a $60 so far to buy a lawn mower. This is 20% of the price of the lawn mower. What is the full price of the lawn mowers that she wants to buy?

--Percent means out of 100, so 20% = 20/100

The prob in other words is asking

- - $60 is 20% of what number?

'$60' - - - - - > 60

'is' - - - - - > =

20% - - - - - > 20/100

'of' - - - - - > * (multiply)

'what number' - - - > x (variable)
