To solve this problem, we need to find the unit rate (the amount of windows cleaned per hour) and multiply by 7. 

To find the unit rate, we need to divide 38 by 2:

38 / 2 = 19

Now, we need to multiply this by 7:

19 * 7 = 133

In 7 hours, the window washer can clean 133 windows. 

Hope this helps!

Answer:

We choose C

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached photo

Basically, interquartile range represents the width or "dispersion" of the set. [1] The interquartile range is determined by the difference between the top quartile (25% highest) and lower quartile (25% lowest) point of the data set.

From the picture, we can find that:

  • The interquartile range of the bus drivers is: 20 -10 = 10
  • The interquartile range of the teachers is: 30 -15 = 15

So the interquartile range of the distances for the bus drivers is 5 miles less than the interquartile range of the distances for the teachers.

We choose C
