Let's review the graph points again to determine Amanda’s earnings correctly.
The points given are:
- (0, 5)
- (0.5, 10)
- (1, 15)
- (1.5, 20)
From these points, we can see that for every increase of 0.5 hours, her earnings increase by $5.
To find her earnings after 7 hours:
- First, identify the pattern. In 0.5 hours, Amanda makes $10. Thus her rate of earning can be derived from these values:
- At 1 hour (from (1, 15)), she makes $15.
- At 1.5 hours (from (1.5, 20)), she makes $20.
The increase in earnings is consistent at $5 for every increase of 0.5 hours.
-
Determine her earnings formula:
- It appears that she earns $5 for each increase of 0.5 hours. Therefore, she earns $10 per hour.
-
Calculate Amanda's earnings for 7 hours:
- \[ 7 \text{ hours} \times 10 \text{ dollars/hour} = 70 \text{ dollars} \]
However, observing the initial points suggests that she is compensated $5 just for being there (starting amount) and earns additionally $5 for each subsequent half hour after the initial half hour.
Therefore, we'd count:
- For the first 0 hours: $5
- For each additional half hour from 0.5 to 7 hours: This can be calculated more accurately.
From 0 to 7 hours is 14 half-hours. So:
\[
\text{Earnings} = 5 + (14 \times 5) = 5 + 70 = 75
\]
Therefore, Amanda will make $75 if she watches them for seven hours. Thank you for your patience!
