Bentley wants to ride his bicycle 39.6 miles this week. He has already ridden 8 miles.
If he rides for 4 more days, write and solve an equation which can be used to
determine x, the average number of miles he would have to ride each day to meet his
goal.



Answer :

Answer:

Step-by-step explanation:

Using a linear function, it is found that he would have to ride his bicycle 7.9 miles a day to meet his goal.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

For this problem, we have that:

  • The 8 miles he has already ridden is the intercept.
  • The daily average he needs is the slope.

When x = 4, y = 39.6, hence:

39.6 = 4m + 8

4m = 31.6

m = 31.6/4

m = 7.9.

He would have to ride his bicycle 7.9 miles a day to meet his goal.
