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 cook
kenny6666 [7]
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.

Chazmire purchases 14 bags of flour for her bakery.Each bag of flour cost $2.47. How much does chazmire soend for flout
solong [7]

Answer:

$34.58

Step-by-step explanation:

If each bag of flour cost $2.47, then;

1 bag = $2.47

To calculate the cost of 14bags;

14 bags = x

x is the cost of 14 bags

Divide both expressions

1/14 = 2.47/x

cross multiply

1 * x = 14 * 2.47

x = $34.58

Hence Chazmire spent $34.58 on flour
