Question

A party of monthly expenses of a family on milk fixed which is rupes 1700 and the remaining varies with the quantity of milk taken extra at the rate of rupee 42 per liter .talking the quantity of milk quantity of milk required extra as x litre and the total expenditure of milk is rupess y. write a linear equation is starting from resprensenting the above information class 9th ml agarwal ​

Answer 1

Answer:

Given Total Expenditure on milk = y rs

Fixed expenses = 1700 rs

Extra expenses = 42 rs/Litre

x litre milk he will buy so total extra expense = 42 *x = 42x rs

So we will get

Total Expenditure on milk = Fixed Expenses + Extra milk Expanses

y = 1700 + 42x

y = 42x + 1700

Standard form of linear equation is is AX+BY = C

y - 42x = 1700

Answer : Linear equation in standard form is y - 42x = 1700

Answer 2

Answer:

Given Total Expenditure on milk = y rs

Fixed expenses = 1700 rs

Extra expenses = 42 rs/Litre

x litre milk he will buy so total extra expense = 42 *x = 42x rs

So we will get

Total Expenditure on milk = Fixed Expenses + Extra milk Expanses

y = 1700 + 42x

y = 42x + 1700

Standard form of linear equation is is AX+BY = C

y - 42x = 1700

Answer : Linear equation in standard form is y - 42x = 1700
