Math in Focus Grade 3 Chapter 4 Answer Key Subtraction up to 10,000 8
At the fair games, Nick has 215 points and Isaac has 78 points. They combine their points to exchange for three prizes.
What are the two sets of three prizes they can get?

a. ________________
Answer:
Three prizes = 2(Pencils) and Pencil holder.

Explanation:
Points of Nick has = 215.
Points of Isaac has = 78.
Total combined points of Nick and Isaac = Points of Nick has  + Points of Isaac has
= 215 + 78
= 293.
Points of pencil = 30.
Points of pencil holder = 200.
Total points of three items  = 2(Points of pencil) + Points of pencil holder
= 2(30) + 200
= 60 + 200
= 260.

b. ________________
Answer:
Three things are Pencil, Notebook and pencil holder.

Explanation:
Points of Nick has = 215.
Points of Isaac has = 78.
Total combined points of Nick and Isaac = Points of Nick has  + Points of Isaac has
= 215 + 78
= 293.
Points of pencil holder = 200.
Points of Pencil  = 30.
Points of Notebook = 50.
Total points of three items  = Points of pencil holder + Points of Pencil  + Points of Notebook
= 200 + 30 + 50
= 230 + 50
= 280.
