Problema Solution
The Big Screamer Coaster carries 92 people altogether. Some of its cars carry 4 passengers, and the rest carry 6 passengers. There are 3 less 6-passenger cars than 4-passenger cars. How many 4-passenger cars are there?
Answer provided by our tutors
Let 'x' represent the number of cars that carries 4 passengers and 'y' represent the number of cars that carries 6 passengers. From the question, we can write:
4x+6y=92
y=x-3
Using Algebrator to solve for 'x' and 'y', we get:
x=11 (4 passenger cars)
y=8 (6 passenger cars)
