Mickey charges $15, $30, $45, and $60 for babysitting 1, 2, 3, and 4 hours, respectively. Is the relationship between the number of hours and the amount charged porportional? If so, find the unit rate. If not, explain
do you not see the relation between hours and money?
Yes but how do I explain my answer?
$15/hr
To determine if the relationship between the number of hours and the amount charged is proportional, we need to check if the ratios of the number of hours to the amount charged are equal for all given values.
Let's calculate the ratios for each case:
For 1 hour: 1 hour / $15 = 0.0667 hours/$
For 2 hours: 2 hours / $30 = 0.0667 hours/$
For 3 hours: 3 hours / $45 = 0.0667 hours/$
For 4 hours: 4 hours / $60 = 0.0667 hours/$
Since all the ratios are equal, namely 0.0667 hours/$, we can conclude that the relationship between the number of hours and the amount charged is proportional.
The unit rate in this case is 0.0667 hours/$, which means that for every additional hour, Mickey charges $0.0667 more.
