Answer:
$22 * (20) + $18 * (48) = $1304
Explanation:
There are 20 reserved seats so it would be: $22 * 20 = $440 for all reserved seats
There are 28 general admission tickets more than reserved seats ticket so number of general admission tickets is: 20 + 28 = 48 (tickets)
Each general admission tickets cost $18, so: $18 * 48 = $864 for all general admission tickets
So the total money was paid for all of the tickets is: $440 + $864 = $1304
