Answer 2

Answer:

Amount of money spend in 1 day =  x

Amount of money spend in 1 day =  xSo, amount of money spend in 7 days =  (7x)

Amount of money spend in 1 day =  xSo, amount of money spend in 7 days =  (7x)⇒  Amount of money spend in 1 week =  (7x)

Amount of money spend in 1 day =  xSo, amount of money spend in 7 days =  (7x)⇒  Amount of money spend in 1 week =  (7x)Amount of money saved in 1 week =  y

Amount of money spend in 1 day =  xSo, 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)

Amount of money spend in 1 day =  xSo, 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)]

Amount of money spend in 1 day =  xSo, 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)
