15% of 1950 = 1950 * 0.15 = 292.5
So, sum would be: 1950 + 292.5 = 2242.5
In short, Your Answer would be $2242.5
Hope this helps!
        
             
        
        
        
Answer:
Experiment
Step-by-step explanation:
An observational study is a study where researchers simply collect data based on what is seen and heard and make inferences based on the data collected.
Whereas, Experimental studies are the ones where researchers introduce an intervention and study the effects. 
Giovanna did not just collect data alone and make inferences based on the collected data, as is done during an observational study, but she studied the effects of the data that she collected by calculating the average driving duration for each route.
Hence we see that she conducted an Experimental study.

Answer:
   (x, y) = (8, 2)
Step-by-step explanation:
The relevant equations are ...
   3x -y = 22
   x +2y = 12
__
We can eliminate y by adding twice the first equation to the second.
   2(3x -y) +(x +2y) = 2(22) +(12)
   7x = 56
   x = 8
Substituting into the first equation gives ...
   3(8) -y = 22
   y = 24 -22 = 2
The first number is 8; the second number is 2.
