Plz which algebraic expression represents “forty times a number”?

40 + n

40n

n – 40

40
_
n

40n

Step-by-step explanation:

(40+n): The first one is asking to add forty and n, however the question is asking for multiplication so that is not an answer.

(n-40): This one is using subtraction, so this one is an obvious no.

(40/n): This phrase represents division, this could be a possibility because it is the inverse operation, however the numbers need to be reversed.

(40n): Im thinking that you got confused because there was no operation symbol. Whenever a number and a variable are attached without an operation symbol in between, you multiply. So, this is the correct answer.

to determine the unit cost your would divide the total cost by the number sold.

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
