Given:

Sol:
Area of picture is:

If the cost $10 per square inch then price of 15 square inch is:

If the quadruple of dimension that mean:

So area is:

So price is:
1/16=1,003, so
senior= 1003
infants=3009
children=6018
adults=6018
Kid tickets = 3d
D = adult tickets
448 = (3 * d) + d
448 = 4d
448/4 = 112
112 = d
3 * d = 336
There are 336 kid tickets and 112 adult tickets sold.
