Answer: The equation to determine the normal price of each cookie is : 7(c-0.75) = 2.80
Step-by-step explanation:
Hi, the correct form of the answer is:
Cookies are on sale! Today each cookie costs $0.75 less than normal price. Right now if you buy 7 of them it will only cost you $2.80!
Write an equation to determine the normal price of each cookie (c)
So, to answer this question we have to analyze the information given:
The normal price of a cookie is "c", if each cookie cost $0.75 less than the normal price, it means:
(c -0.75) = today’s price of a cookie
If you buy 7 of them, 7(c-0.75), it will cost $2.80.
Mathematically speaking:
7(c-0.75) = 2.80
Solving for c :
7c - 5.25 =2.80
7c = 2.80 +5.25
7c = 8.05
c = 8.05/7= 1.15
The normal price of each cookie is $1.15.
Answer:
$ 1.15
Step-by-step explanation:
7(c-0.75) = 2.80 is the equation
$ I.15 is the total for C.
I did this khan before and this is correct!
Hope this Helps!
