Answer

Step-by-step explanation:

si normalmente te dura 4 dias, y supuestamente te llega el 21 de junio durará hasta el 25, lo que quiero decir es que da igual la fecha durará lo mismo de siempre.

First need to make an equation for each

x = Miles
y = Total Cost

Comp A: 120 + 0.20x = y
Comp B: 40 + 0.60x = y

cancel out the amounts to make it easier (Subtract 40 from each)

Comp A: 80 + 0.20x = y
Comp B: 0.60x = y

insert a problem for y to solve for x

 80 + 0.20x = 0.60x

Your answer is 200 miles
