Question

the graph shows the cost of some taxi journeys work out a formula for c in terms of n

Answer 1

$C= \frac{3}{5} n +\frac{5}{2}$

Step-by-step explanation:

From the graph

it is clear that

when n= 0

the intercept at c = $\frac{5}{2}$

intercept at c = 2.5

gradient = $\frac{3}{5}$

then

formula for c in terms of n

is

$C= \frac{3}{5} n +\frac{5}{2}$

hence ,

formula is $C= \frac{3}{5} n +\frac{5}{2}$
