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(14.9A)+9.00A=921.20
5.9014.9=87.91
87.915.90+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?

Best ResponseYou've already chosen the best response.2uh, not quite, remember that A = the number of adult tickets, so it should be a whole number (no decimals!) how about we start over from the very beginning, ok?

Best ResponseYou've already chosen the best response.2ok, we let C = number of child's tickets and A = number of adults tickets, with me so far?

Best ResponseYou've already chosen the best response.0there should be a decimal since it is money right?

Best ResponseYou've already chosen the best response.2think about what A and C represent...

Best ResponseYou've already chosen the best response.2A = number of adult tickets C = number of child tickets there's no such thing as a half a ticket, correct? the number of tickets must be a whole number

Best ResponseYou've already chosen the best response.2well, the problem tells us that "three times as many adult tickets as child tickets were sold" which tells us that: A = 3*C, agreed?

Best ResponseYou've already chosen the best response.2and we know that (price of adult ticket)(number of adult tickets) + (price of child's ticket)(number of child's tickets) = total sales

Best ResponseYou've already chosen the best response.2giving us: 5.90C + 9.00A = 921.20, correct?

Best ResponseYou've already chosen the best response.2now let's work w/ our two equations: A = 3C 5.90C + 9.00A = 921.20

Best ResponseYou've already chosen the best response.05.90(3a)+9.00a=921.20?

Best ResponseYou've already chosen the best response.2A = 3C, so we can replace "A" with "3C" whenever A shows up

Best ResponseYou've already chosen the best response.2giving us: 5.90C + 9.00A = 921.20 5.90C + 9.00(3C) = 921.20

Best ResponseYou've already chosen the best response.2now let's work on the left side of the equation... 5.90C + 9.00(3C) = 5.90C + 27C = 32.9C, agreed?

Vocaloid

Best ResponseYou've already chosen the best response.2so that leaves us with 32.9C = 921.20 do you know how to find C from here?

Vocaloid

Best ResponseYou've already chosen the best response.2yup, divide both sides by 32.9 to find C

Best ResponseYou've already chosen the best response.2check your math again, use a calculator if you aren't sure

Best ResponseYou've already chosen the best response.2other way around, big number divided by small number 921.20/32.9 = ?

Vocaloid

Best ResponseYou've already chosen the best response.2right, so C = 28, and since C is the number of child's tickets, 28 is our answer
