Question 322311
let the base rate be x
the mile rate be y/mile
..
x+625y=210
x+370y= 133.5
..
subtract the two equations
x+625y-x-370y=210-133.5
255y=76.5
y=76.5/255
=$ 0.3/mile
..
plug the value of y in any eauation
x+625*0.3=210
x=210-187.5
x=22.5 base rate
write the equation in the form of y=mx+c and compare the value with m
