Debbie is selling tickets for a spaghetti dinner night. Adult tickets, a, are $10 and children tickets, c, are $5. Sixty percent of the total tickets sold will be given to a local charity. Write a simplified expression to represent how much money will go to the charity.

Proceeds = 10a + 5c
amount going to charity
= (6/10)(10a + 5c)
= 6a + 3c
