Question

At the city museum, child admission is $6.20 and adult admission is $9.80 . on friday, three times as many adult tickets as child tickets were sold, for a total sales of $854.40 . how many child tickets were sold that day?

Answer 1

24 child tickets were sold that day.

Step-by-step explanation

Lets assume, the number of child tickets sold is
`x`

As there are three times as many adult tickets as child tickets were sold, so the number of adult tickets will be
`3x`

Cost of each child ticket is $6.20 and cost of each adult ticket is $9.80

So, the total cost of x child tickets = $ 6.20x

and the total cost of 3x adult tickets = $9.80× 3x = $29.40x

Total amount of sales is given as $854.40 , so the equation will be...

`6.20x+29.40x=854.40\\ \\ 35.60x=854.40\\ \\ x= (854.40)/(35.60)=24`

So, 24 child tickets were sold that day.
