To predict how much Amanda will make if she watches her little cousins for seven hours, we can use the pattern shown in the graph. The points given are (0, 5), (1, 15), and (2, 25).
From these points, we can see the following:
- At 0 hours, Amanda makes $5.
- At 1 hour, she makes $15, which is an increase of $10 from 0 hours.
- At 2 hours, she makes $25, which is an increase of another $10 from 1 hour.
This suggests that Amanda makes $10 for each additional hour she watches her cousins after the initial $5 for 0 hours.
Continuing this pattern:
- At 3 hours, she would make $35 ($25 + $10).
- At 4 hours, she would make $45 ($35 + $10).
- At 5 hours, she would make $55 ($45 + $10).
- At 6 hours, she would make $65 ($55 + $10).
- At 7 hours, she would make $75 ($65 + $10).
Therefore, if Amanda watches her cousins for seven hours, she is predicted to make $75.
