Rs. 5xy^2 + 18 money would be left with her.
Explanation:
Given that,
Money given to Veeena by her mother = 2 xy^2
Money given to Veeena by her father = 7(xy^2 + 3)
Now,
Total money veena has got = 2xy^2 + 7(xy^2+3)
= 2xy^2 + 7xy^2 + 21
= 9xy^2 + 21
A.T.Q.
Money spent by veena on shopping = 3 + 4xy^2
Money left with veena = Total Money Veena has got - Money she spent
= (9xy^2 + 21) - (3 + 4xy^2)
= 9xy^2+21-3-4xy^2
= 5xy^2+18
Thus, 5xy^2 + 18 money would be left with her.
