Answer this question:2 tablespoons of popcorn kernels will make 4 cups of popcorn. For movie night, Joanie wants 3 cups of popcorn, Mitchell wants 4 cups of popcorn, Miles and Davis said they would split 6 cups of popcorn and Cliff said he would only eat 3 cups. How many tablespoons of popcorn kernels will they need?
If Joanie wants 3 cups, Mitchell wants 4 cups, Miles & Davis want 6 cups and Cliff wants 3 cups then they want 3 + 4 + 6 + 3 = 16 cups of popcorn. Every 2 tablespoons makes 4 cups and they want 16 cups so 16 / 4 = 4 groups of 2 tablespoons are needed. Thus they need 4 * 2 = 8 tablespoons in total.
The answer is 8.

Answer this question:In 2021, Wayne is 37 years old. His brother Peter is 3 years older than him and their sister Julia is 2 years older than Peter. What year was Julia born in?
Peter is 3 years older than Wayne who is 37 so Peter is 37 + 3 = 40 years old. Julia is 2 years older than Peter who is 40 so Julia is 2 + 40 = 42 years old. It's 2021 and Julia is 42 years old so she was born in 2021 - 42 = 1979.
The answer is 1979.
