Solution
The correct option is C6 The number of points Jack earns for successfully completing 1 stage is 7.
Therefore, the ratio of the number of points to the number of stages will be 7:1.
Represent this information on a double number line.
The ratio is 7:1. Therefore, 7 will be added to the top line and 1 will be added to the bottom line.
The corresponding value for 35 points is 5. This means Jack has successfully completed 5 stages.
So, is the answer 5?
No!
