Concept explainers

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 …

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experime…

Textbook Question

Chapter 3.7, Problem 4A

Parents with young babies buy a lot of diapers (to say the very least), so getting the best deal is pretty important. Comparing prices can be harder than you would think, though-retailers don’t all sell diapers in the same size boxes. A recent check of prices on Pampers Swaddlers in Size 1 revealed the following:

Amazon.com: 234 diapers for $46.99

Meijer: 160 diapers for $34.99

Find the unit price for each box of diapers and use it to decide which is the best deal. (There’s free shipping, so don’t worry about shipping or tax.)
