Annabelles time for a race was 22.7 seconds. Another runners time was 9.85 seconds faster. Write and evaluate an equation with a variable to find the difference between annabelles time and the other runners time
you don't really need to find the difference using a variable in your equation. You also don't need to know the difference between their times, it is 9.85 regardless. x is 32.55, I think.
