The All-Star A’s baseball team had 23 total runs last week and 31 total runs this week. What was the percent increase in the number of total runs from last week to this week?
a) 34.78%
b) 26.09%
c) 35.29%
d) 25.81%
To find the percent increase in total runs, we need to find the difference in runs and divide it by the original amount, then multiply by 100 to express it as a percentage.
The increase in runs is 31 - 23 = <<31-23=8>>8 runs.
The percent increase is (8 / 23) * 100% = 34.78%.
Therefore, the answer is option a) 34.78%.
