Hello! I suppose the equation is . It may also be
a. Then we see that the number (the free term) is in dollars (or other currency) and it represents the fixed cost. The number
is in dollars by kilometer and it represents the cost per each kilometer driven.
b. It is not difficult to make the table of values, just substitute different values of k to the formula.

b. It is not difficult to make the table of values, just substitute different values of k to the formula.
k | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
A | 1.25 | 6.50 | 11.75 | 17.00 | 22.25 | 27.50 | 32.75 | 38.00 | 43.25 | 48.50 | 53.75 |
Of course each next value is greater than the previous.
c. The graph is attached. Of course this relation is linear (the formula is in the slope-intercept form).
d. The graph shows that for 7.5 km one will be charged $40.625 (probably ).
e. The graph shows that for a person can go as far as about
km.
Of course the results d and e may be found analytically, too. [Tell me if you need this or if the formula is actually 1.25*k+5.25.]
