Please help me, I will medal! Information to read before the question: http://prntscr.com/agwaih Question: http://prntscr.com/agwau9

They want an equation, so it'll be something like \[y = mx+b\] Interesting thing is, all the numbers you need are there
Alright, so how would we do that?
In Y = Mx + B form \[M = Slope\] \[B = Y-intercept\] In this situation M = Cost Per Mile because we're going X miles B = The starting cost, because they have to pay something to use the transportation
Okay, soo I don't know if this helps, but I have 5 questions about this, and one of them says the concert is 10 miles away from your house.. we just have to multiply 0.50 *10, to get the first part, right?
Yep, because you made x = 10
Remember the +B part, B being the boarding cost
0.50 *10 = 5 $5.00 + 6.00 <-- Like that?
Correct, that would be the total after 10 miles
10 miles = $5.00 + 6.00 So << I'd just write something like this as the answer?
It depends on what they wanted If they wanted the equation, you would do y = .05(10) + 6
Alright, awesome! Thanks so much! <3 Do you mind helping me on a few more questions similar to this about the taxi cab, and concert thing?
Yeah, let's see them
This one uses the same equation, we just need to replace the numbers from the first equation with the Taxi-Awesomeness one
y= 0.75 (10) +2 ^^ Is this how this one would look?
Correct, if X = 10 If we don't know what x was, we would just put x instead of 10
For this one, we take both equations we made and make x = 10, since we have to travel 10 miles \[y=(0.5)(10) + 6\] \[y=(0.75)(10)+2\] I would want the cheaper one, so I would solve each of those and see which number is smaller.
Alright, Give me 1 sec
Cabs-r-us: y = .05(10) + 6 y=6.5 Taxi-Awesomeness: y= 0.75 (10) +2 y 9.5 Should I just so this math, and say I'd pick Cabs-r-us because it costs less?
Exactly!
Thank you so much! I would have never understood this without you. http://prntscr.com/agwih0
You're welcome! And this one is the same, you just plug in 20 instead of 10
Actually, lets go back to the 10 mile question I think the calculations may be wrong Let's do (.5) times (10) first, and then add 6 and see what that gets
This is what I wrote down, y = .5(10) + 6. y =6.5 if we do y = .5(10) + 6. y=11
Right it is 11. I was just confused about the 6.5 part, because Taxi-Awesomeness is cheaper in that situation, not Cabs-R-Us
So I should change my reasoning in to picking taxi-awesomeness?
Yes, because (.75)(10) = 7.5 7.5 + 2 = 9.5 9.5 is less than 11
Alright, and in the part after that, choose cabs-r-us, right?
Yep, with the similar mathematical reasonings
Alright, and for the last one, I don't know if I have to show math proof, but I think I should just write "It would be cheapest for me, and her if we both got separate cabs from different cab companies"
Yes, If it is allowed for both of you to get different cabs and meet up at the concert, then that would be the best choice
Awesome. Thanks so much! You seriously rock <3
Anytime =] Always like working with you
Thank you! <3
