Question

A baker sells cookies for $1.50 each. If a minimum of two dozen cookies is ordered, the baker gives a 40% discount for each cookie ordered after the minimum has been met. The cost of an order of cookies after this discount is given by the expression below. Which of the following parts of the expression represents the number of cookies to which the discount will be applied? A 1.5 c B c –24 C 1.5 c –0.4 D 0.4( c –24)

Answer 1

I don't see the expression below.
Since the 40% discount applies to the number of cookies sold above 2 dozen, or 24, then if the number of cookies is c, then c - 24 is the number of cookies above 2 dozen. Answer is B.
