Hiroki's goal is to collect $40 for a school fundraiser. He already collected $26.50. Hiroki wants to know how much more money he needs to collect.
Let m be the amount of money Hiroki still needs to collect. Describe the situation with an equation.
Answers
You subtract 26.50 from 40 which will give 13.50
Hiroki needs to collect $13.50 more.
What is Algebra?Algebra, a discipline of mathematics where abstract symbols rather than concrete numbers are subjected to arithmetic operations and formal transformations. The idea that there is such a separate branch of mathematics, as well as the term algebra to identify it, came about gradually through time. It tries to find solutions to equations that contain one or more unknown quantities. Although early mathematicians would not have been familiar with such a concept, the word "equation" is frequently employed to conveniently represent these operations when discussing the early history of algebra.
As per the given data:
Total amount to be collected = $40
Amount already collected = $26.50
To find the amount of money still to be collected (m):
Total amount to be collected - Amount already collected
= $40 - $26.50
= $13.50
Hence, Hiroki needs to collect $13.50 more.

A booth at the farmer’s market has fresh goat cheese in three sizes of containers. The big container is 30 ounces and costs $9.00. The medium container is 15 ounces and costs $4.95. The small container is 8 ounces and costs $2.00.
Part B
What size is the best buy? Explain your reasoning.
Answers
Answer:
hope u find what your looking for
Part B: The medium container is the best but because it has the lowest price in relation to the amount you are receiving. The big container is 30 ounces and $9. if you divide 30 by 9 you get $3.3333. The small container is 8 ounces and $2. if you divide 8 by 2, you get $4. The medium container is 15 ounces and 4.95 dollars. If you divide 15 by $4.95, you get 3.03030303 which is less money than the other containers. :))
