uh, 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?
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?
think about what A and C represent...
A = 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
well, the problem tells us that "three times as many adult tickets as child tickets were sold" which tells us that: A = 3*C, agreed?
and we know that (price of adult ticket)(number of adult tickets) + (price of child's ticket)(number of child's tickets) = total sales
giving us: 5.90C + 9.00A = 921.20, correct?
so i had that part right
now let's work w/ our two equations: A = 3C 5.90C + 9.00A = 921.20
wait let me gues
almost but not quite...
A = 3C, so we can replace "A" with "3C" whenever A shows up
giving us: 5.90C + 9.00A = 921.20 5.90C + 9.00(3C) = 921.20
now let's work on the left side of the equation... 5.90C + 9.00(3C) = 5.90C + 27C = 32.9C, agreed?
so that leaves us with 32.9C = 921.20 do you know how to find C from here?
would I divide ?
yup, divide both sides by 32.9 to find C
I got an odd number...
check your math again, use a calculator if you aren't sure
921.20/32.9 = ?
other way around, big number divided by small number 921.20/32.9 = ?
ooooo thank you
right, so C = 28, and since C is the number of child's tickets, 28 is our answer
@Vocaloid mind helping me with another one it's my last question
sure, I'll give it a shot
