The problem statement gives rise to two equations, one for the amount of money made, and one for the number of items sold. If x and y represent the numbers of items, and if 53 items were sold, then one of the equations will be ...
x + y = 53
This is sufficient to let you choose the correct answer.

1.40x +1.80y = 79.80
This confirms the choice of answer.
