Baker
Bakers are responsible for making breads, cakes, and other baked goods. They use tools to measure and mix ingredients in specific amounts and a concentrated heat source, such as an oven, to bake their products.
What do you know about bakers?
Did you know that there is some form of baking in almost every culture in the world?
You may have heard the term a baker’s dozen. A baker’s dozen is 13 baked items instead of 12. Here’s why: In order to avoid a fine if their loaves of bread were under a certain weight, bakers would add an extra loaf to every dozen.

Record the total.
Answer:
Explanation:
There are 2 flowers in each flower pot, there are 6 flower pots
2 x 6 = 12 flowers
There are 5 leaves in each pot
5 x 6 = 30 leaves
There are 5 petals for each flower, there are 2 flowers in each pot, there are 6 pots
5 x 2 x 6 = 10 x 6 = 60 petals.
