Answer:
5b + 3m
Step-by-step explanation:
If b represents the cost of a book, then 5b will represent the cost of 5 books
If m represents the cost of a magazine, then 3m will represent the cost of 3 magazines.
To create an expression for the total cost, add these terms together:
5b + 3m
So, the expression for the total cost is 5b + 3m
