Answer 1

Answer:

3. . Amount of money spend in 1 day =  x

So, amount of money spend in 7 days =  (7x)

⇒  Amount of money spend in 1 week =  (7x)

Amount of money saved in 1 week =  y

∴  Income in 1 week =  (7x + y)

So, income in 3 weeks =  [3 x (7x + y)]

=  (21x + 3y)

Answer 2

Step-by-step explanation:

Amount of money spend in 1 day = x

So, amount of money spend in 7 days = (7x)

⇒ Amount of money spend in 1 week = (7x)

Amount of money saved in 1 week = y

∴ Income in 1 week = (7x + y)

So, income in 3 weeks = [3 x (7x + y)]

= (21x + 3y)
