Hey mate!
You stuck?
It shows the expression of the sum of the total miles per hour the car traveled.
Hope this helps! :)
um I dunno because I need points to ask a question sorry
28.50x + 110.99(14-x)=811.45
distribute
28.50 x + 1553.86-110.99x =811.45
combine like terms
-82.49x+1553.86=811.45
subtract 1553.86 from each side
-82.49x =-742.41
divide by -82.49
x=9
He bought 9 of the 28.50 features and 5 of the 110.99 features
