9.) Chan Hee bought 3.4 pounds of coffee. He spent $6.95 per pound.

To solve this problem, you need to multiply 3.4 by $6.95, to find out how much money that Chan Hee spent on the coffee, in total.

3.4 (6.95)

Now try #10 on your own.
Remember that you want to find out the total amount of money Adita earns by multiplying.

Focus on Week Two.
