Ratio 5:2 as fraction should be 5/2
as you know 5/2 = 2.5
This is the biggest compared to 9/5, 8/5 and 2/7
9/5 < 2
8/5 <2
2/7 < 1
so 5/2 is greatest
first we writte the information they are giving to us:
For company A:
initial fee = $90
rent per mile = $2
For combany B:
initial fee = $50
rent per mile = $3
Now for company A the equation that represent the charge in one mile will be: (where n is the number of miles)

Now to determine the number miles driven, that would make the cost of each company the same, we have to make A = B

and finaly we can solve for n

so if they drive for 40 miles the will pay the same
