Miguel parked for 8 hours how much did he pay. For the first hour of park thereof is $1.80. for every additional 1/2 hours or thereof is 0.80

First, we need to determine how many intervals of 1/2 hours Miguel parked for:

8 hours = 16 half-hour intervals

Now we can calculate the total cost:

1 hour = $1.80
7 half-hour intervals = 7 * $0.80 = $5.60

Total cost = $1.80 + $5.60 = $7.40

Therefore, Miguel paid $7.40 for parking for 8 hours.
