Johanna must come up with 800 more dollars in order to pay her college tuition. This number is calculated by multiplying 8,000 by 10% (or .10). When these calculations are completed, you get the number 800. Because the college tuition increases by 10%, calculating 10% of 800 tells you the amount risen due to inflation.
