The Carson family paid $192 for two adult and three youth tickets to an amusement park. At the same park, the Davis family paid
$148 for one adult and four youth tickets. Let x represent the cost of an adult ticket, and let y represent the cost of a youth ticket. Which system of equations can be used to find ticket cost? x+y=192
x+y=148
Since there is no indication of a shift in the graph of f(x) = 3cos(-0.25x), then the midline must be the normal midline for a cosine or sine function which is: y = 0.
