They bought 8 orchestra seats and 6 mezzanine seats.
Step-by-step explanation:
Cost of one orchestra seat = $42
Cost of one mezzanine seat = $25
No. of people = 14
Amount spent = $486
Let,
x be the number of orchestra seats
y be the number of mezzanine seats
According to given statement;
x+y=14 Eqn 1
42x+25y=486 Eqn 2
Multiplying Eqn 1 by 25;

Subtracting Eqn 3 from Eqn 2 to eliminate y;

Dividing both sides by 17

Putting x=8 in Eqn 1

They bought 8 orchestra seats and 6 mezzanine seats.

Answer:
2.22 km
Step-by-step explanation:
Assuming initially both were at the same point ...
Distance from Rico = 5.98 km.
Distance from Josh = 8.2 km in the same direction.
If they were going in the same direction, then the final distance between the two can be written as follows:
d = 8.2 - 5.98 = 2.22 km
After 20 minutes, Rico and Josh were 2.22 km away. of distance between them.
