Answer:
If Ahmad travel 280 miles the cost of both plans will be the same
Step-by-step explanation:
Let's call x the number of miles traveled by Ahmad.
If we say that C1 is the cost of the first plan and C2 is the cost of the second plan then:
C1 = initial fee + additional cost per mile
C2 = initial fee + additional cost per mile
We want to know for what value of x, cost 1 will be equal to cost 2. Then we equate the equations and solve for x.
A) 3x+4=22
B) x=6
How to solve the equation: subtract 4 from both sides. You’re left with 3x=18. What is 18 divided by 3?
Your answer for this is C
It is a observation study, because you are observing how much rainfall is in Hawaii at 50 sites.

So, .
Ankur forgot to put negative sign before 3.
So, The correct option which describes ankur's error is : Ankur found that the quotient of a positive number and a negative number is positive.
Option 3 is right choice.
