Edward went to the market with Rs 4x 2+y2+3y and spends Rs 2x 2+y for a packet of chips and chocolate for the remaining money. How much is the cost of chocolate?​

Edward spent Rs 2 + + 2y on chocolate.

Step-by-step explanation:

Initial amount with Edward = Rs 4 + + 3y

The cost of a packet of chips = Rs 2 + y

By assuming that Edward spent all his money at the market, and on both chips and chocolate. Then;

Amount spent on chocolate = Initial amount with Edward - cost of a packet of chips

                           = (Rs 4 + + 3y) - (Rs 2 + y)

                           = Rs (4 + + 3y - 2 - y)

                           = Rs (4  - 2 + + 3y - y)

                           = Rs 2 + + 2y

Amount spent on chocolate = Rs 2 + + 2y

Therefore, Edward spent Rs 2 + + 2y on chocolate.
