.

Let x be the number of adults under the question. Then the number of children is (1300-x). The money equation is 0.5*(1300-x) + 1.50*x = 1450 dollars. Simplify and solve for x step by step : 650 - 0.5x + 1.5x = 1450 1.5x - 0.5x = 1450 - 650 x = 800. Answer. 800 adults and 1300 - 800 = 500 children. Check. 0.5*500 + 1.5*800 = 1450 dollars. ! Correct !

a + c = 1300
so if we substract the adults what's left is children:
c = 1300 - a
~~~~~~~~~~~~~~~~~~~~~~~~~~
1.50a + 0.50c = 1450
substitute for c:
1.5a + 0.50(1300 - a) = 1450
1.5a + 650 - 0.50a = 1450
1a = 1800
a = 800 this is the number of adults
The children:
1300 - 800 = 500 children

Happy learning!
