Someone please confirm ? if this is right or not.

Problem: Sara needs to take a taxi to get to the movies. The taxi charges $4.00 for the first time, then $2.75 for each mile after that. If the total charge is $20.50,then how far was Sara's taxi ride to the movie?

Equation I came up with is 4.00+2.75X=$20.50 and then subtract from there...

texaschic101 · Answer

you got the equation right..
4 + 2.75x = 20.50 
2.75x = 20.50 - 4
2.75x = 16.50
x = 16.50/2.75
x = 6

check..
4 + 2.75(6) = 20.50
4 + 16.50 = 20.50
20.50 = 20.50 (correct)

Her taxi ride to the movies was 6 miles
