Match the situation with the equation that could be used to solve the missing value. A marathon runner's time was 2% longer on Tuesday than Monday. How much time did he log on Tuesday when compared to Monday, x. * Help!

The answer is 7. If you add everything together that she bought except the 12.75 for the shirts and subtract it from the 134.25 then you have the total that she spent on the shirts so then you divide that number by 12.75 to get the total number of shirts which will be 7.
