To find out who earns more per hour, we need to calculate the rate of earnings per hour for both Piper and Carson.
For Piper:
Using the graph, we find that when Piper works 1 hour, she earns $42. So, Piper's rate of earnings per hour is $42/hour.
For Carson:
Using the table, we find that when Carson works 1 hour, he earns $25.20. So, Carson's rate of earnings per hour is $25.20/hour.
Therefore, Carson earns $42 - $25.20 = $16.80 less per hour compared to Piper.
Therefore, the correct answer is:
Carson earns $16.80 less per hour.
no its not
I apologize for the mistake in my previous response. Let's correct it:
Piper's earnings per hour can be calculated by finding the slope of the line on the graph. To determine the slope, we can choose two points on the graph (0, 0) and (1, 42) to calculate the rise over run.
Slope (m) = (42 - 0) / (1 - 0) = 42/1 = 42
Therefore, Piper earns $42 per hour.
Carson's earnings are given in the table. Carson earns $25.20 for working 1 hour.
Comparing the earnings, we see that Piper earns more per hour: $42 for Piper versus $25.20 for Carson.
Piper earns $42 - $25.20 = $16.80 more per hour than Carson.
Therefore, the correct answer is:
Piper earns $16.80 more per hour than Carson.
no Carson makes 4.20 dollars more an hour
I apologize for the errors in my responses. Let's correct the calculations:
For Piper:
Based on the graph, when Piper works 1 hour, she earns $42. Therefore, Piper earns $42 per hour.
For Carson:
Based on the table, when Carson works 1 hour, he earns $21. Carson earns $21 per hour.
To find out the difference in earnings per hour between Carson and Piper, we can calculate Carson's earnings per hour minus Piper's earnings per hour:
$21 (Carson's earnings per hour) - $42 (Piper's earnings per hour) = $21 - $42 = -$21
This shows that Carson earns $21 less per hour compared to Piper.
Therefore, the correct answer is:
Piper earns $21 more per hour than Carson.
