Adults tickets sold = 321

and children tickets sold = 227

Step-by-step explanation:

Let Adults tickets are represented by x

and children tickets are represented by y

If theater sold 548 movie tickets writing it in algebraic expression we get:

Adults ticket cost $6.50 and a child’s ticket cost $3.50. In all, $2881 was taken in. Writing it in algebraic expression we get:

We need to find value of x and y

Solving the system of equations and finding value if x and y.

and

Let:

Multiply eq(1) wit 3.50 and subtract both equations

So, value of x = 321

Now finding value of y by putting value of x in eq(1)

Value of y= 227

So, Adults tickets sold = 321

and children tickets sold = 227

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
