A taxi charges ₹20 for the first 2 kilometers of travel and ₹x for each subsequent kilometer. If Annie travelled a distance of 25 km, write the expression for the taxi fare paid by her.

total cost = ₹20 + ₹23x

Step-by-step explanation:

She traveled 23 km after the first 2 km.

2 km cost ₹20

23 km cost ₹23x

total cost = ₹20 + ₹23x

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
