loris [4]

Answer:

5n + 10d represented the money spend by the Amy in playing board games  of cost $5 and $10 .

Step-by-step explanation:

As given

Amy and Mary are playing a board game that uses game money if $5 and $10.

At the end of the game, Amy has n bills worth $5 each and d bills worth $10 each .

Total amount of n bills = 5n

Total amount of  d bills = 10d

Thus

Total money spend by the Amy in playing board games = Total amount of n bills + Total amount of  d bills

                                                                                             = 5n + 10d

Therefore  5n + 10d represented the money spend by the Amy in playing board games  of cost $5 and $10 .
