At the movie theatre, child admission is $5.20 and adult admission is $8.60. On Sunday, 132 tickets were sold for a total sales
xxMikexx [17]

Answer:

60 tickets for children were sold

Step-by-step explanation:

Let x be the number of sold children's tickets and let y be the number of adult tickets sold, then we can pose the following equations.

x + y = 132   (i) Because 132 tickets were sold in total

5.20x + 8.60y = 931.20   (ii)   because the total of $ obtained by sales was 931.20.

We must clear x. Then we substitute (i) in (ii)

5.20x +8.60(132-x) = 931.20

5.20x + 1135.2 - 8.60x = 931.20

-3.4x = -204

x = 60
