Question

Three adult and three child movie tickets were purchased for $75. The cost of each child ticket is $3 less than the cost of an adult ticket. The first step to solving this problem algebraically is to write an equation: 3(x+x−3)=753(x+x−3)=75 , where xx  represents the cost of an adult ticket

Answer 1

The equation should actually be:
3(x) + 3(x - 3) = 75
Where x represents the cost of an adult ticket.
