X - number of months ( 1, 2 or 3 );
A function is:
f ( x ) = 50 x + 200
A reasonable domain is:
x ∈ { 1, 2, 3 }
The range is:
y ∈{ $250, $300, $350 }
So first, you add all the numbers together
8.40*3=25.20
12.89*2=25.78
18.90*1=18.90
____________
$69.88
Divide the number of shirts: 6 by the total amount
69.88
_____ = $11.64666= $11.65 is your answer!
6
We have 2.48>2.4 1>2.463. If we insert a '7' between that 4 and 1, we get:
2.48 > 2.471 >2.463, and this is true.
Answer:
Cost of One Journal = $3.99
Cost of One pen = $0.59
Step-by-step explanation:
Let
Cost of One Journal = x
Cost of One pen = y
We can make equation from given statements.
Mr. Bowden purchases 18 journals and 40 pencils for $95.42.

Ms. Jacinto purchases 11 journals and 16 pencils for $53.33.

Now solving these equations to find the value of x

Multiply eq(1) with 2 and eq(2) with 5

We get the value of x is: x=3.99
Now, putting value of x in equation 1 to find value of y.

So, we get the value of y: y = 0.59
Now, finding the costs:
Cost of One Journal = x = $3.99
Cost of One pen = y = $0.59
