The two end points of our line are (0,2.5) and (5,5.5). to find our slope we need to find our n difference (higher value - lower value) and our C difference (same as n) which would be 5 and 3. now we put our cost difference over our miles difference and get our slope (5/3). this means we still need out starting point. which is a cost of 2.5. the equation is C = (slope)5/3n + (starting value)2.5
B. 700
1000 out of 700 is the same as 10 out of 7 but simplified
It is 3 cause i got it wrong and that was the right anser
Number 3 i would say i think it is
