Teresa is ordering an ice cream dessert. She must order a size, a flavor of ice cream, and a topping. There are 3 sizes, 2 flavors, and 2toppings to choose from. How many different ice cream desserts could she order?

She could order 2 ice cream.

12

Step-by-step explanation:

This looks like a perms and coms question. Basically you're just looking for the amount of possibilities that are possible. To do this you would need to multiply all the variables (keep in mind this is different if there are restrictions).

3x2x2=12 different combinations. Good Luck!

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
