Given:

28 members

each member must sell:

10 raffle tickets

5 admission tickets

No price was specified. r is the price of each raffle ticket; a is the price of each admission ticket.

1 member:

10r + 5a

all 28 members:

28 (10r + 5a)

or use distributive property of multiplication:

(28 * 10r) + (28*5a)
