Tickets at the Museum are $5.50 for children and $9.80 for adults. 154 tickets were sold for a total amount $1251.20. How many adult tickets were sold?

Question

So a childs ticket cost $5.50 and an adults ticket cost $9.80. 154 tickets were sold that day for a total of $1251.20. How many adult tickets were sold?

Answer 1

Let x = number of adult tickets.

 

Then (154 - x) = number of children's tickets.

 

Strategy: Money from child tickets plus money from adult tickets equals total money.

 

9.80(x) + 5.50(154 - x) = 121.20.

 

Solve this for x to determine number of adult tickets sold.
