Sally bought 12 tickets for a movie, an adult ticket costs $9 and a child ticket costs $5, if she spent a total of $76, how many adults and children did she buy tickets for?

Answer 1

A = C + 4

9A + 5C = 76

Substitute C+4 for A in the second equation and solve for C. Insert that value into the first equation to solve for A. Check by putting both values into the second equation.

Answer 2

4 x$9.00=$36.00 8 x $5.00 =$40.00
