Answer:
Ryan's revenue last month if he sold 16 new books and 25 old books
is $337.50.
Step-by-step explanation:
The number of old books sold by Ryan = 25
The cost of each old book = $5.50
⇒ Total amount earned by selling 25 old books = 25 x $5.50
= $137.5
The number of new books sold by Ryan = 16
The cost of each new book = $12.50
⇒ Total amount earned by selling 16 new books = 16 x $12.50
= $200
Hence Total amount earned by Ryan
= Amount earned by selling old books + Amount by selling new books
= $137.5 + $200
= $337.50
or, Total amount earned by Ryan = $337.50
Hence Ryan's revenue last month if he sold 16 new books and 25 old books is $337.50.
He found 2x.
When you subtract the outer length of the frame from the outer length of the picture you get the length of the actual exposed frame. To find the length on either side if the picture you would divide by 2 because there are 2 X's. Therefore he found 2x
Using the given property, we conclude that:
f(4) = 8
<h3>
What is the value of f(4)?</h3>
We know that our function has the property:
5*f(x) = f(5*x)
Now, we also know that:
f(20) = 40
Notice that we can rewrite:
f(20) = f(5*4)
Using the above property, we know that:
f(20) = f(5*4) = 5*f(4) = 40
Using the last part:
5*f(4) = 40
f(4) = 40/5 = 8
f(4) = 8
