the cost of one adult ticket is $8
the cost of one kid ticket is $4
Step-by-step explanation:
Let x represent the cost of one adult ticket.
Let y represent the cost of one kid ticket.
They sold 64 adult tickets (x) and 132 kid tickets (y) and made $1040. This means that
64x + 132y = 1040 - - - - - - - - - - -1
An adult ticket is double the cost of a kid's ticket. This means that
x = 2y
Substituting x = 2y into equation 1, it becomes
64 × 2y + 132y = 1040
128y + 132y = 1040
260y = 1040
y = 1040/260 = 4
x = 2y = 2 × 4
x = 8
