Answer:
Step-by-step explanation:
The trip will use six drivers therefore
x+y=6
51x+10y=142 (A bus can seat 51 passengers. A van can seat 10 passengers.)
10x+10y=60
41x=82
x=2 buses
y=4 vans
The total number of bus needed for the trip are 2 and the total van needed are 4.
What is linear equation in two variable?
An equation is written in the form ax + by + c=0, where a, b, and c are real integers and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero.
Calculation for the number of bus and van required;
The total number of people for the trip are 142.
The total drivers are 6.
Let 'x' be the number of bus required for the trip.
Let 'y' be the number of van required for the trip.
So, total number of vehicle will be equal to number of drivers.
Thus, x + y = 6
Again, as one bus can carry maximum 51 passenger.
Total passenger carried by the all bus is 51x.
Similarly, one van can carry 10 passenger.
Total passenger carried by van is 10y.
Therefore, total number of passengers carried by both bus and van will be,
51x + 10y = 142
Solving both equation we get,
x = 2 and y = 4.
Therefore, the total number of bus need for trip are 2 and van needed are 4.
