(b) The man covers a distance of 16 km and gave Rs. 120 to the auto driver. Auto driver
said “It is not the correct amount and returned him the balance. Find the correct
amount paid back by the auto driver.
(c) Which value is depicted here by the auto driver?​

Answer 1

Step-by-step explanation:

a) the equation is

take kilometers as x

and fare as y

so 10+(7x) =y

b) if x = 16

then, 10+(7(16))=y

10+ 112=y

so y= 122 rupees

the correct amount paid back by auto riskshaw is RS 2

c) less
