Let the number of children be c, and the number of adults be a.
c + a = 170 (total number of tickets)
Then the cost of each is: $5.90/child, $9.60/adult:
5.9c + 9.6a = 1269.40 (total sales)
Solving as 2 simultaneous equations, we first transform the first equation:
a = 170 - c
Substitute into the 2nd equation:
5.9c + 9.6(170 - c) = 1269.40
Solving gives c = 98, and a = 170 - 98 = 72. This means that 72 adult tickets were sold that day.
Might be wrong but I might be right so the answer is there is no solution
100+160/500 consist of only vegetarians, or only non-vegetarians, which equal 260/500=13/25 probability. ☺☺☺☺
You have to divide the numerator (the top number) by the denominator (the bottom number). For example: 1/2 is a fraction, its equivalent (equal) decimal is .5. How did we get that? Divide the 1 by the 2 :) I hope this helps :)
