At the city museum, child admission is $5.30 and adult admission is $9.40 . On Tuesday, 140 tickets were sold for a total sales of $1086.40 . How many child tickets were sold that day?
2 answers:
Total tickets sold = # of kid's tickets sold + # of adult tickets sold Total money made = amount of money kid's tickets raised + amount the adult tickets made These can be rephrased as 140 = k + a and $1086.40 = $5.30k + $9.40a Rephrase the first; 140 = k + a a = 140 - k Plug the equation into the first; 1086.4 = 5.3k + 9.4a 1086.4 = 5.3k + 9.4(140 - k) 1086.4 = 5.3k + 1316 - 9.4k -229.6 = -4.1k <span>k = 56 tickets</span>
C + a = 140......a = 140 - c 5.3c + 9.4a = 1086.4 5.3c + 9.4(140 - c) = 1086.4 5.3c + 1316 - 9.4c = 1086.4 5.3c - 9.4c = 1086.4 - 1316 -4.1c = - 229.6 c = -229.6 / -4.1 c = 56......so their were 56 child tickets sold
