Question

A company uses two vans to transport

workers from a free parking lot to the
workplace between 7:00 and 9:00 a.m.
One van has 9 more seats than the other.
The smaller van makes two trips every
morning while the larger one makes only
one trip. The two vans can transport 69
people, maximum. Let x be the seats in the small van and y the
seats in the large van. How many seats does the
larger van have?

Answer 1

Answer : 20 in small , 29 in big as big van has 9 small van

Answer 2

x=20 seats, y=29 seats

Explanation:

y-x=9 y=9+x

2x+y=69 solve by substitution

2x+9+x=69

3x=69-9 3x=60

x=60/3=20 (small van)

y=9+x

y=29 (large van)
