Answer:
b = (c - 3a)/4
Step-by-step explanation:
3a + 4b = c
4b = c - 3a
b = (c - 3a)/4
Not enough info here to enable us to find a numerical answer. We don't know how many cars make up the train.
Suppose that c cars make up the train.
Then the number of seats on this train is 4(c-1) + 2.
Example: if there are a total of 3 cars, the # of seats is 4(2) + 2, or 10:
4 seats in the first car, 4 seats in the second car, and 2 seats in the third car.
To find the mean/average of a set of numbers, add them all together then divide by the number of numbers.
249 + 449 + 269 + 259 + 329 = 1555
1555/5 = 311
The answer is $311

Answer:
1) y=3.5+(5•x)
2) 103.5
3) No, because 5•20 is 100 and 5•10 is 50, BUT with both you still have to add 3.5 no matter what because of the $3.50 to pick up the rider
