Amodel without any simplifying assumptions: a. excludes important predictive variables. b. does not look like the real-world problem it is meant to address. c. is highly complex and likely unworkable. d. provides simplified solutions to complex problems. e. is very for solving tough, real-world problems.
(2 1/2) / (1/4) = 10
in a real world scenario; say you have $2.50 and want to divide into quarters -- how many quarters would you have?
2.50 /.25 ==?
Another example -- you have 2 and a half pizzas you want to give each person at your party 1/4 pie. Haw many pieces can you get out of 2 1/2.
The answer is C.: Is highly complex and likely unworkable
The simplifying assumption is a method that helps us to understand a certain complex system on a much more simpler point of view.
The purpose of creating a model is to make a smaller prototype of an actual system, not the ystem itself. (for example, in a model of Galaxy, it won't include the complex gravitational pulling between the planets)
Alice has 1/4 dozen blueberry mini muffins. For each dozen Alice uses a 2 1/2 cups of flour. How many cups are used in only 1/4 dozen mini muffins?
The answer is 5/8 of a cup of flour. As for the picture I had one planned but, I can't seem to be able to link my drawing. I drew a baking sheet with a dozen of the mini muffins and circled only 1/4 of a dozen of them (3).
REAL WORLD PROBLEM :
You are having a birthday party and invited 38 people. Each table you rented only sits 5 people. How many tables would you need to rent for everyone to have a place to sit? You would have to rent the 8th table for the remaining 3 people to sit at.

a.If you have 2 1/2 cookies and you need to split them up into 4ths, how many cookie peices would you have?
b. 2 1/2 ÷ 1/4= 9/2
c. 2 1/2 ÷ 1/4 = 5/2 × 4/1 = 10 or 4 1/2 cookie peices
The given inequality is
[tex]23m + 4 96[/tex]
Where [tex]m[/tex] represents minutes.
A problem that can be modeled by this inequality is:
Lucy earn $23 per minute, with an extra $4 due to punctuality, which must give more than $96 a day so she can make a living with that job. How many minutes does she need to work?
To solve the problem, we just solve the expression for [tex]m[/tex]
[tex]23m +4 96\\23m 96-4\\23m 92\\m \frac{92}{23}\\ m 4[/tex]
Therefore, Lucy needs to work more than 4 minutes in order to make a living with that job.
Libby wants to make cookies for her whole class. There are 36 students in her class. The recipe Libby is going to use only makes 12 cookies. How many batches of cookies is Libby going to have to make to feed her whole class?
