Answer:
No because the buses are short 2 seats.
Step-by-step explanation:
280 students + 40 adults = 320 people
Bus type A holds 50 people
Bus type B holds 56 people
3 x 50 = 150 seats available for type A
3 x 56 = 168 seats available for type B
3a + 3b = c
3(50) + 3(56) = c
150 + 168 = 318
The buses seat 318 people and cannot accommodate 320 people.
Since 318 < 320, Andre is wrong that 3 of the first type of bus and 3 of the second type of bus will hold all
Number of elementary students going on a field trip = 280
Number of adults going on a field trip = 40
Total number of people going on the field trip = 280 + 40
Total number of people going on the field trip = 320
Let the number of people that the first type of bus can hold be x
x = 50
Let the number of people that the second type of bus can hold be y
y = 56
Number of people that 3 of the first type of bus can hold = 3(50)
Number of people that 3 of the first type of bus can hold = 150
Number of people that 3 of the second type of bus can hold = 3(56)
Number of people that 3 of the second type of bus can hold = 168
Number of people that all the 6 buses can hold = 150 + 168
Number of people that all the 6 buses can hold = 318
Since 318 < 320, Andre is wrong that 3 of the first type of bus and 3 of the second type of bus will hold all
