a store offers a discount of 40% off any regular priced item to price after this discount is represented by S (x). Employees also receive 10% off any purchases; the price after this discount is represented be e(x). Which of the following represents the composite function of applying the store discount first. and the employee discount second?
we have
100%-40%=60%=60/100=0.60
100%-10%=90%=90/100=0.90
S(x)=0.60x
and
e(x)=0.90x
therefore
s(e(x))=0.60(0.90x)=0.54x
answer is
