We know that both Miguel and Sean are heading to the same location, using different routes, but charged the same amount.

Miguel: 2.5+1/4(x)=Sean

Sean: 2.5+1/4(30)+5=(Total Cost of Sean's Trip)
Sean: 2.5+7.5+5=15 (Total Cost of Sean's Trip)

Knowing how much Sean paid for his trip, we can now calculate how far Miguel traveled by solving for x

Miguel: 2.5+1/4(x)=(Total Cost of Sean's Trip)
Miguel: 2.5+1/4(x)=15 (Total Cost of Sean's Trip)
Miguel: 2.5+1/4(x)=15-2.5
Miguel: 1/4(x)=12.5
Miguel: x=12.5*4=50

Add 2 miles to Sean's base so it's $3 + $5. 28 miles remain, so divide 28 by 4 to get $7. So Sean spent $15
Add 2 miles to Miguel's base to get $3. He needs to spend $12 more. 12 x 4 = 48. Add the two miles from the beginning and get 50 miles.

Kudos for a correct solution.


let x=Miguel's distance in miles

2.50 + .25x = 7.50 + .25(30)
.25x = 12.50
x=50

Sean- total amount paid = 2.5+5+(.25*30) = 15

Miguel- lets take ride is x miles,
total amount paid = 15 = 2.5+(.25*x)
then, x = 12.5/0.25 = 1250/25 = 50

Answer - E

Alternate method - lets take Miguel took X miles to airport. (clearly X>30)
Difference of miles = X-30
so, (X-30)*.25 = 5 (amount paid for toll)
X-30 = 20
X = 50

Answer - E

Answer is E ...

With a bit little different approach as guys wrote !!!

since the stem says both people incurred the same cost to reach the airport , we can take equal both sides

the first person incurred : 2.5$ + .25 $ for each mile

the second person incurred : 2.5 $ + .25 $ for each mile + 5 $ for tools

if we take those 2 condition equal , terms 2.5 $ and .25 $ from both sides are cancelled and only remains 5 $ in one side...

so we can deduce in order to both side be equal , the side which is not pay 5 $ must drove more and for each mile driving the side must pay .25 $ so in order to cover 5 $ , that person must drive 20 miles more than the other person. as we are told that the person who paid 5 $ , drove 30 miles, so Miguel must have driven 30 + 20 = 50 Miles !!!!!

So, the answer is E....

Answer = E = 50

Let Miguel travelled = x miles

Both made the same expenditure, so

2.5 + 0.25x = 2.5 + 5 + 0.25*30

\(x = \frac{5}{0.25} + 30 = 50\)

Kudos for a correct solution.


VERITAS PREP OFFICIAL SOLUTION

Correct Answer: E

Explanation: To express this relationship mathematically, we can say that M is what Miguel paid, m is the distance Miguel traveled (in miles) S is what Sean paid, and s is the distance Sean traveled (in miles). Converting the text in the problem to algebra yields:

For Miguel's trip: M = 2.50 + 0.25 * m

For Sean's trip: S = 2.50 + 5.00 +0.25 * s = 7.50 + 0.25 * s

M = S; s = 30

Setting M = S, gives:

2.50 + m4 = 7.50 +

Solve for m:

m/4 = 7.50 - 2.50 + s/4
m/4 = 5.00 + s/4
m = 20 + s

Plug in 30 for s to get m = 50; so the correct answer is E.
