Mr. Brown purchased 15 concert tickets for a total of $200. The concert tickets cost $15 for adults and $10 for children under the age of 12. Write and solve a system of equations to represent the given scenario. Use the
variables "a" for adults and "c" for children.

Which sum or difference identity would you use to verify that cos (180° - ∅) = -cos ∅? a. sin (α -β) = sin α cos β – cos α sin β b. cos (α -β) = cos α cos β – sin α sin β c. cos (α -β) = cos α cos β + sin α sin β d. sin (α + β) = sin α cos β + cos α sin β
