Mr Willis drove 318 miles over 5 days. He drove the same number of miles on the first four days. On the fifth day he drove 3 more miles than the other days

Step-by-step explanation:

Total distance covered, D = 318 miles

Let he drove distance d in each first four days

distance covered in fifth day = 3 + d

So, the total distance covered = 4 x d + 3 + d = 5d + 3

According to the question

5d + 3 = 318

5d = 315

d = 63

So, he cover 63 miles in each first four days and fifth day he cover 63 + 3 = 66 miles.

Sample Response: The equation of Relationship 1 is y = 3/2x + 5. Substitute 50 for y and solve to find that x = 30. Multiply 30 by 5/6, the rate of change of Relationship 2, to get 25. This means that the initial value would need to be 25 to get to 50 when the input is 30.
