at the city museum , child admission is 5.50 and adult admission is 8.90. on thursday, four times as many adult tickets were sold for a total sales of 943.30. how many child tickets were sold that day?

22.9

Step-by-step explanation:

Alright, so here you need to create an equation. If we say that the number of child tickets sold is x, and the number of adult tickets sold is y, we can create two different equations. Because child tickets cost 5.50, and adult tickets cost 8.90, we can say that 5.50x + 8.90y = 943.3. Another equation we can make is 4x = y, because 4 times as many adult tickets were sold. Then, we substitute 4x for y in the first equation and solve. 5.59x + 8.90(4x) = 943.3, 41.19x = 943.3, and x ≈ 22.9, which means y ≈ 91.6. It is strange that these numbers are noth exact, as should be with tickets, but these are the answers you get by solving.
