If tickets cost $8 each, each tells me that I will need to multiply something. I don't know how many girls and boys this group will have the problem does not tell me, so I will just use the variable "x" to stand for that number. $8 times x will equal the total cost in dollars for the tickets. So the expression would be 8x = total or just 8x.
The Answers are B and C Its B because 12 is MORE than twice as much as M. Meaning 140 is larger than 2*m Its C because again it is MORE than twice as much as M. Meaning that 140 is larger than 2m.
