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
