Richard spent $8 for 1 magazine and 2 puzzle books.At the same store Christopher spent $23 for 4 magazines and 4 puzzle books.How so you write a system of equation to represent the situation?

Answer 1

I assume you want a system that you can solve for the cost of a magazine and the cost of a book,

m = cost of magazine

b = cost of book

The given information translates into

1m + 2b = 8

4m + 4b = 23

Solve for m and b. The answers will be in $.
