Jerry bought some pens and pencils in the ratio of 2:5.
After he sold 270 pencils and `1/4` of the number of pens, the ratio of the number of pens to pencils became 3:8.
A pen can be sold at a price of $1.20
The selling price of a pencil is `7/12` of the selling price of a pen.
The total cost inccured by Jerry to buy all the pens and pencils was $388.
If Jerry managed to sell all the pens and pencils he had, how much money would he earn?
