Question

Howard is putting napkins on tables at a restaurant. Each table gets the same number of napkins.

• After putting napkins on 6 tables, Howard has 124 napkins remaining
• After putting napkins on 10 tables, Howard has 108 napkins remaining
How many napkins does each table get ?

Answer 1

Each table gets 4 napkins

Explanation:

Rate of change

It usually refers to how fast one quantity changes with respect to another. We are given the following information.

After putting napkins on 6 tables, Howard has 124 napkins remaining

After putting napkins on 10 tables, Howard has 108 napkins remaining

This means that Howard used 124-108=16 napkins in 10-6=4 tables.

The rate of change (or rate of use in this case) is 16 napkins/4 tables= 4 napkins per table.

Each table gets 4 napkins
