Melissa will rent a car for the weekend. She can choose one or two plans. The first plant has no initial fee but costs $.80 per mile driven. That's like a plan has an initial fee of $75 in cost an additional $.38 per mile driven. How many miles with Melissa need to drive for two plants to cost the same? NEED HELP ASAP PLEASE

Respuesta :

If you equal both of the PLANS you will get
$.80x=$75+$.38x
then you subtract .38x on both sides and get
$.42x=$75
once thats done you will divide .42 on both sides leaving the variable x by itself...
and then x=178.57miles
but to break even it would be 179 miles for both of the plans to cost the same
