Question is not proper, Proper question is given below;
For a birthday party, Mr. Perkins orders 8 chocolate chip cookies and 16 sugar cookies. Each cookie is the same price. He also picks up a cupcake for himself, which costs $2.75. The total bill is $44.03. What is the cost of a cookie?
Answer:
The Cost of the cookie will be $1.72.
Step-by-step explanation:
Given:
Mr Perkins orders 8 chocolate chip cookies and 16 sugar cookies.
Since cost of both the cookies are same then Let us assume the cost of cookies be 'x'.
Total cost of the cookies =
Cost of Cup cakes = $2.75.
Total bill he pays = $44.03
We need to find the cost of each cookies.
Now we know that Total bill he pays is equal to sum of Cost of cookies and Cost of Cup cakes he bought.
Framing in equation form we get;
Now Subtracting both side by 2.75 using Subtraction property we get;
Now Dividing both side by 24 using Division property we get;
Hence The Cost of the cookie will be $1.72.
Equations can be solved in several ways; one of these ways is the graphical method.
The number of commercials, x, and the number of movies, y, on which Naomi's songs were played are 5 and 2, respectively.
Let:
<em /><em> commercials</em>
<em /><em> movies</em>
<em />
She earned a total of $300.
This is represented as:
Her songs were played on 3 more commercials than movies.
This is represented as:
See attachment for the graphs of
From the graph, the lines of both equations intersect at:
This means that:
- <em>The number of movies is 2</em>
- <em>The number of commercials is 5</em>
