Answer:
48.51%
Step-by-step explanation:
We can find the percent of increase in decimal form by dividing the final amount of yards that Nathan ran by the amount he ran at the end of the first half like so...
75 / 50.5 = 1.4851
Now in order to turn this decimal into a percentage, we need to subtract 1 and multiply by 100.
(1.4851 - 1) * 100 = x
0.4851 * 100 = x
48.51% = x
Finally, we can see that the percent of increase in the number of yards that Nathan carried the ball from the end of the second half to the end of the game was 48.51%
