What strategy would be the best to solve this problem?
A theater charges $8 for an adult ticket, and $6 for a children's ticket. On a certain day, a total of 255 tickets were sold for a total cost of $1,850. How many more children's tickets were sold than adult tickets?
A. guess, check and revise
B. use a formula
C. work backwards
D. look for a pattern
By making an equation where x = number of adult tickets and y = number of children tickets, we can get 2 equations: 8x + 6y = 1850 x + y = 255 then we solve the equation to get each of the amounts
