Would anyone mind helping me to see if I did this correctly?
At the city museum, child admission is $5.90 and adult admission is $9.00.On Sunday, three times as many adult tickets as child tickets were sold, for a total sales of $921.20.How many child tickets were sold that day?
C+A=14.9
5.90C+9.00A=921.20
5.90(14.9-A)+9.00A=921.20
5.90-14.9=87.91
87.91-5.90+9.00A=921.20
-3.1A=833.29
CANCEL OUT THE -3.1 AND DIVIDE 833.29 BY -3.1A =268.80
SO WOULD IT BE A=268.80?

ok, we let C = number of child's tickets and A = number of adults tickets, with me so far?

there should be a decimal since it is money right?
