Answer:
Explanation:
1) The first step is to find the common difference of the table so that we know the amount you need to pay per person without counting the vehicle cost.
2) We can find this by doing (20-14)/(4-2)=3. Just to check, we can do (32-20)/(8-4)=3.
3) Using the hint, we know that the vehicle cost is $8, but if you want to find it, you should do 14-2X(the value per person)=14-2X3=8.
4) So, if there are 30 people on the bus, in order to find the value you need to pay, you must do 30X3+8=98.
5) So the answer is 98.
