Step-by-step explanation:
Let x = number of child tickets sold.
Cost of x child tickets is x * 5.30 = 5.3x.
"three times as many adult tickets as child tickets were sold"
Number of adult tickets sold: 3x
Cost of 3x adult tickets is 3x * 8.40 = 25.2x
Cost of all tickets is 5.3x + 25.2x = 30.5x
Cost of all tickets is $1189.50
30.5x = 1189.5
x = 1189.5/30.5
x = 39
Answer: 39

- The domain of the attachment graph .

The method to identify the domain and range of functions is by using graphs :-
⚡ The domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis .
⚡ The range is the set of possible output values, which are shown on the y-axis .
See the attachment figure .
[NOTE :- Keep in mind that if the graph continues beyond the portion of the graph we can see, the domain and range may be greater than the visible values .]
✍️ So, we can observe that the graph extends horizontally from -3 to the right with +10 .
✯ Hence, the domain is [-3 , 10] .
By estimating. 5x700 is 3500. i multiplied the first digits in the equation.
there are 10 tens per hundred
5 x 10 = 50 tens for five hundred add 4 tens
so 54 tens
