2 truck company’s and when the miles will cost the same

Question

60d+ .60m = 30d + .60m. Need to find when m or miles are both the same

Answer 1

60d +.6m = 30d +.6m

60d = 30d

2d = d

d = 0, when the number of days rented =0 the cost is the same

they cost the same when the number of days rented =0

but odds are good you mis-copied the problem or the problem itself was typed incorrectly
