Explanation:
Hi, to answer this question we have to write an equation with the information given.
We have to subtract to the amount that Alejandra paid(x) the sum of the costs of each product [videogame (24), controller (13) and memory card (169] and the total tax (3). the expression must be equal to the amount received in change.
Mathematically speaking:

x = 4+56
x =60
