x= miles travel

anonymous · Answer

you are given the cost and want the miles

anonymous · Answer

you've got $330 to spent total, but you have to spend $250 on the car for the week, leaving you with $80 for the miles. question is, at $0.10 per mile, how far can you go on $80 ?

anonymous · Answer

another way to express this is, if $x$ is the number of miles,  solve $0.10x=80$ for $x$

anonymous · Answer

Oh I just plugged in the answers and i came up 800. 1.10(800)+250=330

anonymous · Answer

i meant 0.10 not 1.10
