Answer:
t = Total Amount
m = Miles driven
Express Movers: t = 25 + 0.80m
Smith & Smith Co: t = 35 + 0.60m
Step-by-step explanation:
The 25 and 35 are constants, and the 0.8m & 0.6m are variables of miles. So, you add the constants to the variables for each mover to get the amount of money that it will cost total per mile.
