Let x be the number of children and t, the number of adults.

x + y =153
5.2x + 8.4y = 1013.2

Solving those equation will give:

x = 85 tickets sold to the kids ( and 68 tickets for adults)

Running at the same constant rate, 5 identical machines can produce one lot containing a certain number of toys per hour. At thi

Answer:

$1.6\cdot{x}$

Step-by-step explanation:

If the speed is constant for 5 machines and produces x amount of toys we know that rate is defined as a constant per time:

Here the machines are constant and the rate is x toys per hour:

If 5 machines make x per hour:

Rate is x/1 hour

The the ratio of 8/5 is 1.6. Therefore for 8 machines the rate is 1.6 times more per hour than for5 machines. Therefore we can write an expression as:

Rate for 5 machines is x and for 8 machines is y:

$y=1.6\cdot{x}$
