Which table below has the same rate of change as Moobers? Select all that apply
To determine the rate of change for Moobers, we can see that for every 50 miles driven, the cost increases by $20.
The rate of change for Moobers is $20 / 50 miles = $0.40 per mile.
Now, we need to identify which tables below have the same rate of change as Moobers:
Table 1:
- For every 30 miles driven, the cost increases by $15
- Rate of change = $15 / 30 miles = $0.50 per mile
Table 2:
- For every 40 miles driven, the cost increases by $20
- Rate of change = $20 / 40 miles = $0.50 per mile
Table 3:
- For every 70 miles driven, the cost increases by $30
- Rate of change = $30 / 70 miles ≈ $0.43 per mile
Based on the calculations, both Table 1 and Table 2 have the same rate of change as Moobers.
