Percent decrease = (change in value) / (original value)
change in value = 9965-10100 =-135
We will just use 135 because the negative just that the value decreased
original value = 10100
So 135 / 10100 = .0134
This is a decrease of 1.34%
850/630= 1.35 exchange rate
150x1.35= 202.50
The solution would be undefined, since it is not possible for 10 to be equal to -15. Hope this helps! :)
50 + .35x = 75 + .25x
.1x = 25
25 divided by .1 is 250
going back and checking my work:
50 + .35 (250) = 137.5
75 + .25(250) = 137.5
So the answer is 250 miles
