Solution

The correct option is A $(20a + 15c)
Price of entry ticket for an adult = $$ 20$
Total number of adults in the family = $a$
Price of tickets for $a$ number of adults = $$ 20 a$

Price of entry ticket for a child = $$ 15$
Total number of children in the family = $c$
Price of tickets for $c$ number of children = $$ 15 c$

Total amount of money required to purchase the entry tickets for the family = price of tickets for $a$ number of adults + price of tickets for $c$ number of children $= $ (20 a + 15 c)$
