Question 922391: In car park A, it costs 4 AED to park for the first hour, and an extra 11 AED for each hour after that. In car park B, it costs 6 AED to park for the first hour, and an extra 5 AED for each hour after that. Your dad turned to you for help in order to choose the cheaper car park. You-having learnt about linear equations, rates of change, and slopes- went to work on solving your father’s problem. You decided to illustrate the solution of the problem to your father in three ways: in table of values, graph and algebraic solution.
1) Write a linear equation that models the number of hours parked as the independent variable and amount money paid as the dependent variable in each of the car park.

You can put this solution on YOUR website!
Let +C+ = the cost of parking
Let +n+ = total number of hours parked
For car park A:
+C+=+11%2A%28+n+-+1+%29+%2B+4+
for car park B:
+C+=+5%2A%28+n+-+1+%29+%2B+6+
