He history museum is hosting a special exhibition on history of flight. The admission ticket for each adult costs $3 and the admission ticket for each child costs $2. On the opening day of the exhibition, 60 tickets were sold for a total of $160. How manyadults visited the special exhibition?

20

Step-by-step explanation:

Given that :

Adult admission :

Adult (a) = $3

Children (b) =$2

60 tickets were sold :

a + b = 60 - - - (1)

Cost of tickets sold :

3a + 2b = 160 - - - (2)

From (1):

a = 60 - b

3(60 - b) + 2b = 160

180 - 3b + 2b = 160

180 - b = 160

180 - 160 = b

20 = b

Number of adults :

a = 60 - b

a = 60 - 20

a = 20

Hence, 20 adults visited the exhibition
