The Science Club needs to rent a bus for a field tripe. M.S. Buses charges a $40 rental fee, plus $2 per mile. C.B. Buses charges a $20 rental fee, plus $3 per mile. For what number of miles will the total be the same? What will the charge be?

You can  put this solution on YOUR website! The Science Club needs to rent a bus for a field tripe. M.S. Buses charges a $40 rental fee, plus $2 per mile. C.B. Buses charges a $20 rental fee, plus $3 per mile. For what number of miles will the total be the same? What will the charge be? 
How would I solve this problem? 
Write a cost equation for each statement and make them equal to each other 
: 
Let m = no, of miles for this to be true 
: 
" M.S. Buses charges a $40 rental fee, plus $2 per mile.  
C = 2m + 40 
: 
"C.B. Buses charges a $20 rental fee, plus $3 per mile." 
C = 3m + 20 
: 
3m + 20 = 2m + 40 
now just solve for m, then find the cost by replacing m with that value in both equations. 
If you did it right, they should be equal.
