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:
<em>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!
</em>
<em>Write an equation to determine the normal price of each cookie (c)
</em>
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.
180-94-41 = 45
180-45-111 = 24
The answer is x is 24 degrees
Let's say one pipe can fill 1/10th of the swimming pool per hour; and the other can fill 1/8th of the pool per hour. Then, working together they can do:
1/8+1/10=5/40+4/40=9/40 pool per hour
1 pool/(9/40) pool/hour=40/9 hours for one pool when the pipes are working together

The area of the circle A and B is 86.54 inches and 124.62 mm
According to the statement
we have given that the radius of the circle A and b and we have to find the area of the given circle.
So, we know that the
The area enclosed by a circle of radius r is πr².
So, For area of the circle
For condition A :
diameter = 10.5 inches
then radius = 5.25
Area = πr²
Area = 3.14*27.56
Area = 86.54 inches
Now, For condition B :
radius = 6.3 mm
Area = πr²
Area = 3.14*39.69
Area = 124.62mm
So, The area of the circle A and B is 86.54 inches and 124.62 mm
