• Let a = number of adults, c = number of children. System: a + c = 1175, 5a + 3.5c = 5087.5. Solution: a = 725, c = 450.

• Let a = number of adults, c = number of children. System: a + c = 1175, 5a + 3.5c = 5087.5. Solution: a = 600, c = 575.

• Let a = number of adults, c = number of children. System: a + c = 1175, 5a + 3.5c = 5087.5. Solution: a = 800, c = 375.

• Let a = number of adults, c = number of children. System: a + c = 1175, 5a + 3.5c = 5087.5. Solution: a = 500, c = 675.

• It is reflected over the x-axis, shifted right by 4 units, and up by 1 unit.

• It is shifted left by 4 units and down by 1 unit.

• It is stretched vertically and shifted down by 1 unit.

• It is compressed horizontally and shifted up by 4 units.

Given the graph to the right, name the parent function and compare it to the given graph.

• The parent function is f(x) = |x| and the graph is reflected over the x-axis.

• The parent function is f(x) = √x and the graph is shifted right.

• The parent function is f(x) = 1/x and the graph is shifted left.

• f(3) = 8, g(2) = 8, so f(3) + g(2) = 16.

• f(3) = 9, g(2) = 6, so f(3) + g(2) = 15.

• f(3) = 7, g(2) = 9, so f(3) + g(2) = 16.

• f(3) = 8, g(2) = 6, so f(3) + g(2) = 14.
