Which strategies can be used to solve this problem?

Rosa organized a game day at her house. She plans to have 2 groups of 5 people play charades, and 3 groups of 4 people play board games. What is the greatest number of people who could be at Rosa's game day?

Choose all answers that are correct.

A. Draw a diagram.

Draw 2 squares and 5 circles. Then draw 3 squares and 4 circles. Add the total number of squares and circles.

B. Use logical reasoning.

Think that finding 2 groups of 5 is the same as 2 * 5 = 10 and that 3 groups of 4 is the same as 3 * 4 = 12. Then add 10 + 12.

C. Model the problem.

Show 2 groups of 5 chips and 3 groups of 4 chips. Then count all the chips.

D. Translate into an equation.

2 * 3 * 4 * 5 = n
