In London, the charge of a tour bus consists of a fixed rental price plus a per kilometre rate, that depends on the distance of
ella [17]

Using a linear function, we have that:

a) The fixed cost is of $10.

b) The equation is: C = 10 + 12d.

c) The cost of an 18 km trip is $226.

d) The distance traveled is of 20 km.

<h3>What is a linear function?</h3>

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, the slope is of m = 12. When d = 5, C(d) = 70, hence we find the fixed cost as follows:

C(d) = 12d + b

70 = 60 + b

b = 10.

Hence the equation is:

C(d) = 12d + 10.

For a trip of 18 km, d = 18, hence the cost is:

C(12) = 12 x 18 + 10 = $226.

When the cost is of $250, the distance is found as follows:

250 = 12d + 10

12d = 240

d = 240/12

d = 20 km.

In a survey of college students, each of the following was found. Of these students, 355 owned a tablet, 292 owned a laptop, 280
avanturin [10]

Add all the numbers together to find the total amount of college students surveyed.

355 + 292 + 280 + 191 + 198 + 136 + 66 + 24 = 1,542

The number is already simplified considering it's a whole number. The answer is either 1,542 or 1,500

<em>(I say either because when it says to simplify I'm not sure if they want it to be rounded.)</em>
