Answer:
There are 11 four person passengar cars
Step-by-step explanation:
let's call the number of four person cars A , & the number of six person cars B
there are 3 less 6 person cars than 4 people cars which can be written as:
A - 3 = B
there are also 92 total people that can go on max on the whole ride which can be written as:
4A + 6B = 92
Now we need to subsitute in our first equation into the second, so:
4A + 6(A-3) = 92
then distrbute the 6:
4A + 6A - 18 = 92
bring like terms to the same side & consolidate:
4A + 6A = 92 + 18
10A = 110
divide the right by # of A to get a single term :
A = 110/10
A= 11
