A local sporting event charges $6 for each adult ticket and $3.50 for each child ticket. If the stadium sold a total of 65 adult and children’s tickets for a total of $340, how many adult tickets were sold?
Subtract a from the equation on top to get b = 65 - a Substitute into the second equation 6a + 3.5(65 - a) = 340 Simplify to make 6a + 227.5 - 3.5a = 340 6a - 3.5a = 340 - 227.5 Combine like terms so that 2.5a = 112.5 Divide both sides by 2.5 to isolate the variable a
