If it costs $3.47 for 12 lemons, then we will set it up using this:
3.47/12 = x/1
Where x is the amount of money you pay for just one lemon.
3.47/12 = x/1
3.47 = 12x
3.47/12 = x
.29 = x
So you paid $.29 for each lemon.

Your proportion can be 12/3.47 = 1/x. Now cross multiply and you get 12x = 3.47. Divide both sides by 12. You get .288 which rounded to the nearest hundredth (because our money system only goes to hundredths) you get $.29 per lemon.
