At the city museum, child admission is $5.90 and adult admission is $9.20 . on thursday, three times as many adult tickets as child tickets were sold, for a total sales of $1273.00 . how many child tickets were sold that day?

Respuesta :

Let's have x be the number of children tickets and 2x will be the adults. Now we can set up the following equation:
5.4x+8.9(2x)=626.4
Expand this out:
5.4x+17.8x=626.4
Combine like terms:
23.2x=626.4
Divide both sides by 23.2 to get x=27
