Yiping takes a Lyft home from the soccer game. He uses Lyft Premier, which costs $5 plus $2.30 per mile, and his bill comes to $22.25. How many miles did he travel?

Yiping traveled 7.5 miles

Explanation:

The equation is  5 + 2.3x =  22.25

Subtract 5 from both sides.

2.3x=22.25−5

Subtract 5 from 22.25 to get 17.25.

2.3x=17.25

x=    

Expand

 by multiplying both numerator and the denominator by 100.

x=  

result is 7.5
