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?
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
