The percentage decrease was 13%. If you subtract 1,300,000 from 1,500,000, you will get 200,000. You then divide 200,000 by the original number 1500,000 and you will get 0.13333333333333...
After you do that multiply that number by 100 and you will get your percentage.
(1,500,000-1,300,000=200,000)
(1,500,000/200,000=0.13333333333...)
(0.1333333333333X100=13.33333333...)
and then just round
The answer would be 79 r 1
Hope this helps! :)

Step-by-step explanation:
Answer:
f(x) = x*3/4 + 42.5
Step-by-step explanation:
The original difference between the pair is 70 - 30 = 40
The new difference between the pair is 95 - 65 = 30
Since the differences are not the same, Mrs Bailey must first perform a (slope) multiplication by a factor of 30/40 or 3/4
Then 30 * 3/4 = 22.5
Then she can shift the scores up by 65 - 22.5 = 42.5 in order to get the range from 65 to 95
Therefore, f(x) = x*3/4 + 42.5. We can test that
f(30) = 30*3/4 + 42.5 = 65
f(70) = 70*3/4 + 42.5 = 95
