A library had a used book sale for 4 days. The library paid $25 for an advertisement each day of the sale and sold each book (b) for $2.00. The expression below represents the amount of money the library raised at the book sale. How much money was raised when 400 books were sold per day?
Answer:
1,982
Step-by-step explanation:
i got It right on edge 2020
The library raised $320,100 when 400 books were sold per day.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Number of days book sale = 4
The library paid for advertisement each day = $25
Cost of each book (b) = $2.00.
The expression represents the amount of money the library raised at the book sale.
= 4(25) + 2b(400)
Now,
Substitute b = 400 into the expression.
= 4(25) + 2(400)(400)
= 4(25) + 320000
= 320100
Therefore,
The library raised $320,100 when 400 books were sold per day.

Answer:
66789
Well you never told to explain :/
Not tryna be smart just saying
Answer:
66789
Step-by-step explanation:
3 times 3 is 9, 3 times 4 is 12 carry the 1, 3 times 5 is 15 plus the 1 is 16
Add a 0 underneath the other numbers, 2 times 3 is 6, 2 times 4 is 8, 2 times 5 is 10
Add two 0's 1 times 3 is 3, 1 times 4 is 4, 1 times 5 is 5
Add all of them and you get 66789
Which expression shows another way to write 36+16?
4(9)+4
4(9+4)
6(6+8)
(6+4)(6+4)
Answer:
36+16= 52
4(9)+4= 40, which does not equal 52.
4(9+4) = 52.
6(6+8) = 84, which does not equal 52.
(6+4)(6+4) = 100, which does not equal 52.
So, 4(9+4) is correct.
