to and from school : 0.6 + 0.6 = 1.2 per day
for 5 school days : 1.2 x 5 = 6 miles per week
57.5 cents per mile : 57.5 x 6 = 345 cents = $ 3.45
not exactly sure how to make it an equation
y = 57.5x....where x = number of miles per week and y = total cost
I am not 100% sure on this equation....kinda seems like there should be more....sorry
