Answer:
1.9 miles.
Step-by-step explanation:
John jogs 2 7/10 miles to the park. Marsha jogs 4/5 miles to the park.
Convert the fractions into decimals:
2 7/10 = 2.7
4/5 = 0.8
Subtract '0.8' from '2.7':

John should jog 1.9 miles farther than Marsha. 
Hope this helps.

Answer:

So then the correct answer is B. $200.
Step-by-step explanation:
Notation 
Let X be the average contribution size before John makes his contribution.
Let Y be the total contribution size before John makes his contribution.
Let Z be John's contribution.
We know that for this case $ 75 represent the original average amount before the contribution with 50% increase so we can set up the following equation in order to find the original average amount

And solvong for X we got:

Now we can find the total contribution before the donation with the following proportion:


And then with the formula of average taking in count the 6 values we can find the size of donation Z like this:



So then the correct answer is B. $200.
