3. A store offers a discount of 40% off any one regular-price item. The price paid after this discount is represented by $(<). Employees also receive 10% off any purchases; the price paid alter this discount is represented by e(x). Which of the following represents the composite function of applying the store discount first, and the employee discount second?
O e(s(x) = 0,043
O c(s(x)) = 0.542
Os(e(x) = 0.542
Os(e(x)) = 0.042
