The rate of change represents the <em>variable production</em> cost rate. The <em>production</em> cost is increased in 1200 units per each <em>additional</em> manufactured car.
<h3>
Interpretation of a linear function</h3>
Let be
and
the production cost and the number of vehicles produced, it there is a <em>linear</em> relationship between the two variables, then we have the following formula:
(1)
Where:
- Fixed production costs.
- Variable production cost rate.
In a nutshell, the rate of change represents the <em>variable production</em> cost rate. The <em>production</em> cost is increased in 1200 units per each <em>additional</em> manufactured car.

2 and 5 are prime and thus share no common factors. The lowest common multiple of 2 and 5 is therefore 2 x 5 = 10.
Your answer must be a multiple of 10 and there is only one answer in that range that fits.
Double-check:
110 / 2 = 55 r. 0
110 / 5 = 22 r. 0
