Step-by-step explanation:
Answer:
Selling Price of the Book - $7.70
I believe that this is the answer
Step-by-step explanation:
We need to find what is 40% of 5.50.
40/100 x 5.50
After solving this, we will get 2.20
Now, the question is asking what is the selling price of the book will be after it is marked up. Marked up means an increase in price, and the increase in price is 40% of 5.50 which we have already found. All there is left for us to do is add 5.50 and 2.2. This will give us $7.70.
For this case, the first thing we must do is define variables:
x: number of pillowcases
y: number of sheets
We now write the system of equations:
2x + 5y = 40
x = 2y
Solving the system we have:
x = 8.9
y = 4.4
Answer:
The maximum number of pillowcases she could have purchased is:
x = 8 (spent less than $ 40)
300+400+6 that's the answer
