How many tickets did the amusement park sell on Saturday?

Question

An amusement park sells child and adult tickets at a ratio of 8:1, On Saturday, they sold 147 more child tickets thank adult tickets. How many tickets did the amusement park sell on Saturday?

Answer 1

Hi 

Let a= Number of adult tickets sold

Then number of child tickets sold = 147 + a

The ratio =( a + 147 )/ a= 8/1

a+147 = 8a

 

7a = 147

a= 147/7 = 21

 

Number of child ticket = 147 +21 = 168

So total tickets sold  = 168 +21 = 189
