Well, 40 - 8 = 32, since she had 8 remaining. Then divide 32 by 2, since she gave 2 to each of her friends. Therefore, she has 16 friends.
-- Driving at 30 mph for 20 minutes (1/3 hour), you cover 10 miles.
-- Walking at 3 mph for 10 minutes (1/6 hour), you cover 0.5 mile.
-- Average speed = (total distance covered) / (time to cover the distance)
= (10.5 miles) / ( 1/2 hour)
= 21 miles per hour.
Answer:
Step-by-step explanation:
Even though you didn't provide options from which to choose, you don't need them to figure out the system. We need an equation that involves the NUMBER of people and then we need an equation that involves the MONEY earned. Two different things here.
As for the number of people, we know that the number of adult tickets + the number of children = 12 people, so
x + y = 12.
That's the first equation. Now for the money:
21.50x + 14.75y = 204.00
That's your system.
