Answer:
x + 338 = 550.
Explanation:
Total distance from Atlanta Georgia to Orlando Florida = 550 miles.
Distance GEN traveled yesterday = 338 miles.
Number of miles she drove today + Distance GEN traveled yesterday = Total distance from Atlanta Georgia to Orlando Florida.
If we take she drove x miles today, we could write an equation as
x + 338 = 550.
In order to find the number of miles she drove today, we need to solve the above equation for x.
