Unitary Method
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 miles away.
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 experiments to set up the devices.

The library was hosting a book-signing event for a popular author of children's books. It advertised
a free juice box and small bag of pretzels for all children who attended the event. The librarian
anticipated that no more than 200 children would attend the event, but 257 children showed up.
Use this information to answer parts 1–4.
1. The librarian had purchased 200 juice boxes for $136. She sends Pat and Chris to the store to
buy juice boxes for the extra children. If they find juice boxes for the same unit price, how much will
they spend on the additional juice boxes?
They will spend $ 38.76.
(Type an integer or a decimal.)
2. Pat and Chris go to a different store where they can buy 2 juice boxes for $1.25, but the rate does
not apply to single juice boxes. How much more or less will they spend on juice boxes at this store?
Explain.
Because they need to buy the juice boxes in groups of 2, they will need to buy 58 juice boxes. So,
29 pairs of juice boxes for $1.25 a pair is a total of $ 36.25 which is $ 2.51 .less than $38.76.
